Thank you!! We are not leaving the iron head community out in the cold. We are actually developing combos that are making the iron head crowd make more power than they have before! Bigdogs stage 2 iron heads, Bigdogs stage 2 cam and our stage 3 ported short runner gt40 style manifold is a winning combination that is HARD to beat!! Stay tune and you will see more results
Nice, I got my 70 Windsor heads Pushing pretty much same power as aluminum AFR's, Took alot of time and valve sizes. but It worked. Stock appearance is a must for the class im running.
Aluminium heads are always better....for removing money from your pocket. Over the years, I've spanked plenty of big dollar motors with alloy heads with modified factory cast iron heads. Just because it's cast from aluminium, it doesn't mean it's better
Exactly!! On top of that many of the Aftermarket Aluminum heads don't hold up as far as durability wise. We see so many that are pitted and eaten away by coolant and also warped and wear out faster. They tend to only last for 20,000-30,000 miles before issues if that
How much money do you have in your iron heads and do you think that you would have run faster if you started with a pair of aluminum heads rather than iron heads before maximizing your setup and working your heads? It comes down to the setup so yes there are countless people with mismatched setups running slow with aluminum heads then there are those who know how maximize a setup along with put that power to the ground running damn fast with aluminum heads.
@msk3905 a customer can get their set of Gt40P heads fully stage 2 ported with our upgrade PAC valve springs for less than $720. That's not even our Stage 2 max porting! A set of tfs 170 as cast heads are currently $1,650-$1,800. So for the average street/strip guy looking to bolt on a good performing head onto his 302/306 that want to last over 100,000 miles then our stage 2 gt40p heads are the better deal. Besides they can always buy one of those ebay turbo kits and make 600-650whp lol. To me I can't see myself spending almost $2,000 on some heads that only flows 245-250int/175-180ext at .600".
@@bigdogsportingtonyb2833 there is definitely a place for those GT40 heads and I get your point but i paid $500 for my worked E7 heads then $1200 for my twisted wedge (some time back) and what I experienced was a significant improvement in performance after swapping out. Going fast isn’t cheap, what I learned was don’t skimp on heads and cam all my opinion. Also, as so many do I ended up building a 332ci stroker after I feel that I maxed the 302 combo that the Twisted Wedges supported.
@@msk3905 what were the flow numbers of your E7 heads? That's my point. Go look up the price of as cast tfs 170s, they will run you $1,700-$1,800 now. That's my point. We are not talking about your worked E7s with no flow data that's using the same bench to flow both heads. We are talking about our stage 2 ported Gt40P heads that are flowed on the same bench using the same fixtures tested the same way and the majority of people have 302s or 306s not stroker motors. See you don't see what we see as a manufacturer. When you are talking about tens of thousands or millions then there are far more people running 302s or 306s than there are people running 331, 347, 363 0r 408s combined lol. What we are doing is bringing high level porting to the market at a much affordable price which people are not use to, same as with the manifolds. Before us you would had to pay $2,000 or more to get what we offer in our stage 2 porting on iron heads which was out of the question for most so that's why people are in shock now but many well known and respected porters knew what the iron 40s and Ps could do. No one in the industry is offering so much porting and services to those heads at our price except us. To get a factory ford iron head with the valve size of 1.85/1.46" to flow what we get them to flow is not common and we are doing them in production. We will do a direct flow comparison video against some common aluminum heads to show you. I've personally ran 10.80s on a set of our Stage 3 Race prepped Gt40 heads that flowed high 240s/195s on a friend's SF600 back in the 2010s.
Those of us with an 1986 shorblock don't have valve reliefs... with the GT40 stage 2 heads work? I have been told aftermarket heads don't work well on these 86 motors.
@@badlilstang our stage 2 ported E7s work with stock cam and flow much better than stock gt40s. Our Stage 2 gt40 heads will work with a .045" head gasket and stock cam but like always check the ptv clearance.
Peak flow is only part of the equation, flow dynamics, port velocity, reversion, low lift flow characteristics, combustion chamber flame travel and quench etc all play a role together for overall power output. Just like all the engines they build in magazines...they advertise that peak number, because it sells the shit out of parts. You gotta look at the rest of the curve. When he swapped out the stage 2 ported gt40 heads for SVE's theres a possibility it may have made slightly more peak Horsepower for sake of argument, but probably not, but it probably gutted the low end torque and midrange power , knocked all the meat out of the curve. 289/302s are ultra sensitive to intake runner size and intake valve size. Too big, and you'll have a torqueless pooch. Sub 450hp you are better off with a smaller intake valve and port that is professionally ported, blended and tuned via flowbench like yall do, then a large as cast port and large valve. Same thing with Cams and Carburetors too .... Bigger ain't always better.
His et and mph were both down. He said 3 tenths and 2.5 mph consistently. Our stage 2 ported iron heads are nothing like the average porting most have seen on them. We do a whole lot to them that is on a different level. Our short side shapes are designed to work with our valve seat angles and valve mods, our roof and bowl height and shapes are designed to boost the ports discharge coefficient nature, our chamber work and shape is designed for a good balance of tumble and swirl and improved scavenging. We do certain mods to aid in the exhaust scavenging of the chambers to allow a bigger percentage of incoming air/fuel charge. We have a lot of R and D into iron head porting. The SVE heads has terrible exhaust and lower lift flow especially having a 2.02/1.60 valve setup which is exactly the opposite of what you want in a head. If the head can't get rid of all the spent gases then there's less room for the fresh mixture to occupy results are less power. On top of them retaining less heat(energy).

Honestly , up to 450hp for a street strip deal even with a 331, a prepped ported and carefully gone through GT40 head is hard to beat. Especially guys like me running small cubic inch windsors in heavy vehicles like trucks and vans and sedans. If you must have aluminum, get afr 165s and have them ported. Youll keep your Torque and throttle response. But you gotta stay on top of cooling system maintenance and valvetrain adjustments. Aluminum heads dont have the longevity for street burners like a iron head does.
I have as cast AFR 165s on a 393w, bought it from a friend who built it as a Tq engine in a '94 RCLB 2wd ZF5 S42 F250 with 3.55s, bas a lightning lower, Explorer upper BBK 70mm TB 95 Cobra MAF, Doug's long tubes, Y'd into a 3.5" MBRP diesel single, 185° tstat, electric fans, converted to a mustang Sequential MPFI instead of batch fire, 1.6 rockers, 5.0 HO factory cam. It makes great tq, falls on its face past 5000rpms, decent on fuel, will run 87oct with Octane booster, gets 12-18mpg between empty and towing depending on city or highway. I would guess it makes 350-400hp 450-500tq depending on the tune and fuel. I really want to put more cam in it, port the heads or go with TFS 11R 190-205cc heads, highrise single plane, Holley Sniper or 850cfm carb. Have also considered a $1400 Scat 408 stroker assembly or building a custom 4.030" bore 4.25" stroke 434 stroker bottom end with an extra '97 351w roller block I have . If money was no object I might buy an aftermarket block and build a 4.150" bore 4.25" stroke 460w. The only thing these days that makes a big Windsor build less appealing is the new 7.3 Godzilla blocks which are $1,500 for a new short block $650 each for new assembled heads and stroker kits available from Callies up to 4.250" bore 4.6" stroke making a 522ci stroker.

@@highoctane9050 what customers don't understand is this type of work is done mostly by hand. To get these factory iron heads to flow like we do is extremely difficult.

You typed a whole lot and could have typed less with an answer. I’m sure we all would like to know together those types of things in preparation. Thanks for taking the time to comment back though. I will be in touch.
Sometimes the customer is wrong, my buddy just got done with building a 347 for a guy, dart block, High dollar lunati stroker kit, cnc 205 11r, he was not interested in a custom cam so it was recommended to use a N91 Anderson, he refused he wants a b cam, we tried to explain its to small and will severely limit the performance, he stood firm and now is pissed because his buddy has a stock block, eagle stroker with untouched 190 11r and is nearly a second faster in the 1/8, due in large part to the .691 lift custom ground cam, it pulls clean to the chip at 7800 where the b cam is all in and done by 6500 pretty much
Yes they are. We tried to tell this customer before but he bought cheaper Aluminum heads not knowing the science and went slower and now he is going to sent those Aluminum heads in to get ported which is spending unnecessary money. He could have kept his stage 2 gt40s and just got our stage 2 cam and stage 3 Explorer upper and made more power than he will even with the stage 2 ported SVE heads alone.
You can contact us on our Facebook business page or Google page at Bigdogs Porting for our current prices and ordering information. We can get you great power on a budget!
Very nice. Looking forward to see how my 3800 heads turn out.... alot of 3800 guys are hoping they turn out great.... F*ck them forums, a bunch of haters no matter what forums your on ,Foxbody or Wbody. Big Dogs rocks
We did a before and after flow video on your heads because Lamont said you had a lot of people waiting on the results. We couldn't go crazy because those 3800 heads are crack prone but we did make some great gains especially where it counts!!
Yeah there is NO ONE left porting 3800 heads. I kno the Wbody(GrandPrix GTP) Is a dieing platform but there a still a bunch of guys looking for a proven porter. I'm hoping they turn out extremely nice and you guys get a whole bunch more customers that want there NON cracked 3800 heads. Lamont knows what I went through trying to find good castings for you guys to do your thing
SVE heads out of the Box ore the Iron heads ported .?? how much is port Job for the Iron heads ? and you have still double of the weight ... buy Alu Heads and port them a little ... and strap them on a Dyno engine and lets see how much they make ... thats real testing because I want HP numbers not Flow numbers ...also doesnt say if the SVO are the 170 or 185 .....
No, you're not understanding the comparison. There's a lot more to consider that most don't understand until it's too late and exactly why their combos under perform. It takes 100lbs to equal 10hp and the difference in two average aluminum heads vs two gt40p iron heads in weight is around 35llbs. Our stage 2 Explorer gt40 manifold is 5-6lbs lighter than a Systemax 2 manifold as a companion. Also our ported Iron Gt40P Heads makes more hp than the SVE heads when using cams with .540" lift or less and the stage 2 ported Iron Gt40P Heads are more durable, don't fall apart and last a lot longer than the out the box SVE heads. This is exactly why we port and sell so many of them. You'll be lucky to get 30,000 miles out of a typical set of aftermarket aluminum heads before they need some work vs our stagec2 ported Iron Gt40P Heads that will last over 100,000 miles. We see hundreds of heads a year and these aftermarket aluminum heads come in beat up, pitted, seats loose, warped, bad valve jobs and not flowing what they should.
And we've had well over 500 aftermarket aluminum heads come to our shop with less than 30,000 miles on them than didn't hold up and needed full rebuilding. We deal with thousands of parts not just one or two. Thanks 😊
@bigdogsportingtonyb2833 ALL depends on how the engine the heads were on was treated maintenance wise. A idiot can break a anvil, Most aftermarket name brand heads, not Chinese cast junk, are better made than OEM aluminum heads and all new cars today have aluminum heads. So if aluminum heads are junk after 30k miles why are all car manufacturers using aluminum heads??
@@BlueByYou07 we see thousands of parts. These aftermarket heads are not designed with longevity in mind. They pit up bad, drop seats, guides wear our fast, warp, threads strip and many burn oil. This is not even a debate. We see thousands of parts and have a better view on what we see. Others see the same things and have also made posts and videos. Thanks
@bigdogsportingtonyb2833 I'm 50yrs old and ran a mustang performance shop from 1994-2009. I myself installed hundreds of sets of aftermarket aluminum heads on customers cars that where 9,10 and 11 second street cars making 450hp to 1200hp. Now what I did see come in my shop were heads INSTALLED incorrectly the first time without checking pushrod length and setting up rockers not centered on the valve. Now your DEFINITELY gonna get heads that wear out guides and beat seats to death early from not setting up your valvetrain properly. Pitting in the coolant comes from the owners using hard water and not the correct coolant. Now that happens all the time with OEM aluminum heads.
@@BlueByYou07 this is not even a debate lol. I just don't understand why people are always trying to tell us we are wrong when we see this stuff every single day. If you don't agree then just don't watch the videos. All this back and forth won't change anything 🤣. Everyone don't want a set of aluminum heads and Everyone don't need a set of aluminum heads to go fast! I went 10.80s with our stage 3 ported Explorer, stage 3 ported Iron Gt40s l, our stage 3 cam, 4,200 stall converterwith our other parts NA at 3,100lbs years ago lol. We know how to port them and make them last.
You are making all good points and your flow numbers below 0.300” are impressive but it comes down to the setup and setting up your heads correctly, sorry but you put a set of E7TE, GT40, GT40P, etc. then put a good set of aluminum heads in someone who knows how maximize a setup and work heads to maximize performance they will always run faster with the better flowing aluminum heads. Back in the day I had a set heavily ported E7s with 1.94x1.6 vlvs that was a blast, ran great and made 270rwhp then upgraded to just TF Twisted Wedges with same cam, put down 304rwhp with more torque across entire TQ curve. 100% street car and was breaking tires much quicker and more frequently. Next I wanted to maximize that setup so installed a cam better suited for heads and saw more TQ gains along peak HP jumping to 317rwhp.
You are correct but you also just proved one of our points. The term heavily ported means nothing to us because we've seen plenty of heads that were heavily ported but flowed like crap. This is exactly why we flow text everything because we know looks mean nothing. As cast tfs 170s are good heads and we've ported over a hundred of them yet their out the box average flow of the as cast is only a few cfm from our stage 2 gt40p heads considering our stage 2 gt40p heads have much smaller values which makes them the more efficient, lower costing and longer lasting head.most of the popular streetable cams lift is below .530" so flow at .600" lift means nothing to the majority. Your heavily ported Iron heads that only made 270whp must have not flowed well because our stage 2 ported Gt40P stock valve heads routinely make 340-360whp with our stage 2 kits (will providea link to one). This is why we provide before and after flow results because we know all porting is not the same. We've also seen a few of our customers make as much as 380whp with our ported Gt40P heads and a more aggressive setup on 306s. Our porting on these parts is different from Others and we wish people would stop thinking there're the same, because there're not. How many porters have you seen get a Explorer gt40 manifold to make over 400whp naturally aspirated in a street car besides us? That's my point😊
This is a car that's running our complete stage 2 gt40p kit and on a Dynojet with a T5 without a computer tune and full Accessories it put down 352whp/349wtq. Hp peaked right at 6,000-6,100rpm and was held back by the factory rev limiter. We setup this car ourselves in the shop as it was not setup and dialed in correctly from tge previous installer. Most don't know how to dial these combos in for peak performance. th-cam.com/video/Jx179_yGYfQ/w-d-xo.htmlsi=mwGWM-3Derd_6Q-a

Sometimes the customer is wrong, my buddy just got done with building a 347 for a guy, dart block, High dollar lunati stroker kit, cnc 205 11r, he was not interested in a custom cam so it was recommended to use a N91 Anderson, he refused he wants a b cam, we tried to explain its to small and will severely limit the performance, he stood firm and now is pissed because his buddy has a stock block, eagle stroker with untouched 190 11r and is nearly a second faster in the 1/8, due in large part to the .691 lift custom ground cam, it pulls clean to the chip at 7800 where the b cam is all in and done by 6500 pretty much
Yes they are. We tried to tell this customer before but he bought cheaper Aluminum heads not knowing the science and went slower and now he is going to sent those Aluminum heads in to get ported which is spending unnecessary money. He could have kept his stage 2 gt40s and just got our stage 2 cam and stage 3 Explorer upper and made more power than he will even with the stage 2 ported SVE heads alone.
Man I wish you was out in Kansas City!!!
We are just a ups shipment away lol
The proof is in the pudding 😅 i got 70 351 w heads on 363 w port work and 194 160 vavles 12.5 compression and is a hand full in the street

You can contact us on our Facebook business page or Google page at Bigdogs Porting for our current prices and ordering information. We can get you great power on a budget!
Very nice. Looking forward to see how my 3800 heads turn out.... alot of 3800 guys are hoping they turn out great.... F*ck them forums, a bunch of haters no matter what forums your on ,Foxbody or Wbody. Big Dogs rocks
We did a before and after flow video on your heads because Lamont said you had a lot of people waiting on the results. We couldn't go crazy because those 3800 heads are crack prone but we did make some great gains especially where it counts!!
@bigdogsportingtonyb2833 hell yeah. I'm patiently waiting, thank you Lamont & Tony
Yeah there is NO ONE left porting 3800 heads. I kno the Wbody(GrandPrix GTP) Is a dieing platform but there a still a bunch of guys looking for a proven porter. I'm hoping they turn out extremely nice and you guys get a whole bunch more customers that want there NON cracked 3800 heads. Lamont knows what I went through trying to find good castings for you guys to do your thing
@@bigdogsportingtonyb2833 you ever tried porting blowers??
@@jplperformance9073 we have ported many of them. We've posted results on the page before
Hell good stuff to know. I got some SpeedMasters for my 393. I know who to send them too😂
Those speed masters need a lot of help. Our cam would be great as well
@@bigdogsportingtonyb2833 that’s the plan👍
Port the exhausts and better intake valve job on the SVE’s and add a 0.600” lift cam and see what happens!
Our Stage 2 on the sve heads gets them flowing like 11R heads

So whats better Edelbrock performer heads or gt40 max flow2.5? For street strip car. 306? Weekend car no hp goals just where it works optimal???
Our stage 2 Gt40p heads blows the out the box performers out the water. And they will Kay for a long time.
SVE heads out of the Box ore the Iron heads ported .?? how much is port Job for the Iron heads ? and you have still double of the weight ... buy Alu Heads and port them a little ... and strap them on a Dyno engine and lets see how much they make ... thats real testing because I want HP numbers not Flow numbers ...also doesnt say if the SVO are the 170 or 185 .....
No, you're not understanding the comparison. There's a lot more to consider that most don't understand until it's too late and exactly why their combos under perform. It takes 100lbs to equal 10hp and the difference in two average aluminum heads vs two gt40p iron heads in weight is around 35llbs. Our stage 2 Explorer gt40 manifold is 5-6lbs lighter than a Systemax 2 manifold as a companion. Also our ported Iron Gt40P Heads makes more hp than the SVE heads when using cams with .540" lift or less and the stage 2 ported Iron Gt40P Heads are more durable, don't fall apart and last a lot longer than the out the box SVE heads. This is exactly why we port and sell so many of them. You'll be lucky to get 30,000 miles out of a typical set of aftermarket aluminum heads before they need some work vs our stagec2 ported Iron Gt40P Heads that will last over 100,000 miles. We see hundreds of heads a year and these aftermarket aluminum heads come in beat up, pitted, seats loose, warped, bad valve jobs and not flowing what they should.

352whp combo that will last for over 100,000 miles! SVE heads won't last lol. We know 😊
What would be a good head setup with the 86 stock short block ??
Depends on hp goals
@@bigdogsportingtonyb2833 1200 !!! Lol
Gotta see what pistons I have first !!! But love the channel keep up the good work
I put over 100k miles on a set of Canfield heads and Edelbrock VictorJr heads with zero problems.
And we've had well over 500 aftermarket aluminum heads come to our shop with less than 30,000 miles on them than didn't hold up and needed full rebuilding. We deal with thousands of parts not just one or two.
Thanks 😊
@bigdogsportingtonyb2833 ALL depends on how the engine the heads were on was treated maintenance wise. A idiot can break a anvil, Most aftermarket name brand heads, not Chinese cast junk, are better made than OEM aluminum heads and all new cars today have aluminum heads. So if aluminum heads are junk after 30k miles why are all car manufacturers using aluminum heads??
@@BlueByYou07 we see thousands of parts. These aftermarket heads are not designed with longevity in mind. They pit up bad, drop seats, guides wear our fast, warp, threads strip and many burn oil. This is not even a debate. We see thousands of parts and have a better view on what we see. Others see the same things and have also made posts and videos.
Thanks
@bigdogsportingtonyb2833 I'm 50yrs old and ran a mustang performance shop from 1994-2009. I myself installed hundreds of sets of aftermarket aluminum heads on customers cars that where 9,10 and 11 second street cars making 450hp to 1200hp. Now what I did see come in my shop were heads INSTALLED incorrectly the first time without checking pushrod length and setting up rockers not centered on the valve. Now your DEFINITELY gonna get heads that wear out guides and beat seats to death early from not setting up your valvetrain properly. Pitting in the coolant comes from the owners using hard water and not the correct coolant. Now that happens all the time with OEM aluminum heads.
@@BlueByYou07 this is not even a debate lol. I just don't understand why people are always trying to tell us we are wrong when we see this stuff every single day. If you don't agree then just don't watch the videos. All this back and forth won't change anything 🤣. Everyone don't want a set of aluminum heads and Everyone don't need a set of aluminum heads to go fast! I went 10.80s with our stage 3 ported Explorer, stage 3 ported Iron Gt40s l, our stage 3 cam, 4,200 stall converterwith our other parts NA at 3,100lbs years ago lol. We know how to port them and make them last.
You are making all good points and your flow numbers below 0.300” are impressive but it comes down to the setup and setting up your heads correctly, sorry but you put a set of E7TE, GT40, GT40P, etc. then put a good set of aluminum heads in someone who knows how maximize a setup and work heads to maximize performance they will always run faster with the better flowing aluminum heads. Back in the day I had a set heavily ported E7s with 1.94x1.6 vlvs that was a blast, ran great and made 270rwhp then upgraded to just TF Twisted Wedges with same cam, put down 304rwhp with more torque across entire TQ curve. 100% street car and was breaking tires much quicker and more frequently. Next I wanted to maximize that setup so installed a cam better suited for heads and saw more TQ gains along peak HP jumping to 317rwhp.
You are correct but you also just proved one of our points. The term heavily ported means nothing to us because we've seen plenty of heads that were heavily ported but flowed like crap. This is exactly why we flow text everything because we know looks mean nothing. As cast tfs 170s are good heads and we've ported over a hundred of them yet their out the box average flow of the as cast is only a few cfm from our stage 2 gt40p heads considering our stage 2 gt40p heads have much smaller values which makes them the more efficient, lower costing and longer lasting head.most of the popular streetable cams lift is below .530" so flow at .600" lift means nothing to the majority. Your heavily ported Iron heads that only made 270whp must have not flowed well because our stage 2 ported Gt40P stock valve heads routinely make 340-360whp with our stage 2 kits (will providea link to one). This is why we provide before and after flow results because we know all porting is not the same. We've also seen a few of our customers make as much as 380whp with our ported Gt40P heads and a more aggressive setup on 306s. Our porting on these parts is different from Others and we wish people would stop thinking there're the same, because there're not. How many porters have you seen get a Explorer gt40 manifold to make over 400whp naturally aspirated in a street car besides us? That's my point😊
This is a car that's running our complete stage 2 gt40p kit and on a Dynojet with a T5 without a computer tune and full Accessories it put down 352whp/349wtq. Hp peaked right at 6,000-6,100rpm and was held back by the factory rev limiter. We setup this car ourselves in the shop as it was not setup and dialed in correctly from tge previous installer. Most don't know how to dial these combos in for peak performance.
