    Thanks so much for such an informative and well-organized video on 350 heads. The more a person knows; the more of an expert they are, the more humble they are (usually). When you said, "I don't know everything, but I know a lot", I knew right there that you know what the hell you're talking about. Other guys that don't know 1/10th of what you know will say, "I know everything about 350 Chevy heads!" I wish other TH-camrs that do informational videos took the time to get organized and chock their videos with as much info as you do. Hopefully some of them will check out your videos, because they could learn a lot (and not just about how to film videos)! Thanks again for such great info and presenting it so well.

    Excellent, Most accurate info about SBC heads I have watched in many years. Been building street engines since the mid 70's. Now with 49 Years experience (Now 2022). My pick has been 041 since I first found them at Pick-A-Part in the late 70's in the Valley (SFV). Were produced for only 2½ years. Very hard to find Then... I would assume almost impossible to find now. 186 Castings were easier to find. Well Done.

    You should have said something about the 441 heads, lingenfelter wrote in his book. Them 1969 heads with the 2.02 intake and 1.60 exhaust valves are the true LT1 heads they experimented the year before they released them onto the 350 LT1 motor. Every one else also has a bad habit of calling fuelly heads as 2.02 intake and 1.60 exhaust valves, but actually the first Fulie motor was in the Corvette with the 327 motor in 1963 I think? But these heads had actually 1.94 intake valves and 1.50 exhaust, they named these heads the Fulie because of the fuel injection, great article, maybe you can do a special on the Fulie heads, LT1, and the 441 heads to educate people better on these heads. Have a good night my friend.

    I have a 1973 Corvette C3 L48 195 HP 350 engine with "882 smog crap" (76cc chamber) heads, but to keep the car number matched I reworked and gasket match the crappy stock iron heads, installed screw fit rocker studs, kept the small 1.94 stock valve size but changed to new Manley stainless valves and bronce guides, gave the seats a rework too...enlarged the intake runners a little... Chevy V8 Engine block got TRW made forged new old stock 0.30 oversized LT1 copy domed pistons on pink LT1 forged rods giving 10.5:1 static CR with the L48 76cc heads, pistons and rods weight matched, original cast crank in 2 bolt block remained only got a cleaning and ballancing, Camshaft is a LS46 GM cam copy by Elgin (E921p Duration At .050" Lift 224/224, Intake Valve Lift:.450" Exhaust Valve Lift:.460" ) ...intake manifold is a Edelbrock performer with 750 Edelbrock quad carb...engine runs like a champ giving German 350 DIN HP (Not SAE) on rolling road, pretty much like the original 1970 LT1 and L46. It does not need lots of expensive trick stuff to get a decent street performance engine.

    FYI: TrickFlow is going into production with an aluminum version of the 461 head with a slightly larger intake runner(175 CC as opposed to 170 CC) already set up for high lift cams. It will be budget oriented so it will be competitively priced to factory SBC head with the machine work to support the same type of valve train.

    Thanks for all your research and posting this. Coming from LS and small block Ford I am building my first gen 1 small block from all free parts that people have given me over the years. It's a little junker 355 and someone gave me a pair of 993 heads that have been ported and valve job with 2.02/1.60. The big chamber should put me at 9:1 but that's ok. 87 octane turd.

    The 3987041 and 3987041X in particular were used as a warranty replacement heads in matched set for the 69 Z28 Camaro. My DZ Block cracked and the CE wedge piston replacement block came with 3987041X heads. I still own the Camaro today and wish you had noted the oversized intake and exhaust ports of the 041X heads.
    The X can be found on the bottom of the intake runner, if you've never seen one. If you want a Pic I have plenty.

    I know this is old... But still very relevant info.
    I'm also a former Engine Builder and Machinist.
    YES - totally agree with you on the 624 Heads!! JUNK! There's enough of the others to not use them.
    Now I have "successfully" built a few 350s with 305 Heads.... Do I suggest that the average person do it - NO. I even used 58cc Chamber 305 Heads with Dish Pistons, giving 10.6-1 Compression....
    THE DIFFERENCE - I explained to the Customer that these would NOT be high revving, high Performance Engines! What they were, with Port Matching and mild Polishing and a Comp Cams 268H, was a Truck Torque BEAST. Fantastic from IDLE to 3500, but pretty much ran out of poop by about 4400-4800, with significant Torque loss between 3800 to Redline. Guys even reported getting significantly better Fuel Economy when not getting into it!!
    THAT was the late 70's to early 90's.... After that, it became obvious that you could practically "have your cake and eat it too" with a 383 Stroker! Possibly the best Chevy Small Block that Chevy never made.
    I'm really enjoying your Channel. You really know your shit, and have even taught me a few new things!!
    None of us know everything - it's always good to gain knowledge from someone who has had different experiences. 😉

    Raced several yrs. running Hobbystocks, ran Double humps then those were outlawed and ran a lot off 993s, 882, But the best heads we found were the 441 and the 441X. These heads were what everyone wanted back in the day. Now everyone who doesn't run Crate motors run the EQ heads.

    I hope my combination runs decent. I went with a 355 running flat tops with a xe268 with a set of 186 1.94/1.50 valves. Basic porting to clean up the casting flash. Edelbrock rpm intake, Edelbrock 600, 2400 stall 350 turbo and a set of 3.42's
    All of this is going in a 79 cutlass. Hopefully it'll run hard for a street car and pull lower 13's, should be very streetable. Might step up to some RHS Vortecs one day.

    There is another machinist on here that talked about date codes on heads. He stated he found over the years that you could tell by the day of the week differences in quality of the heads... He said he noticed that Monday and Friday heads took the most work to shape them up. That Tuesday-Thursday heads were of better quality workmanship... Nobody wants to be at work on Monday or Friday...

    We've built about a dozen IMCA modified SBC and I can tell you the 041 angled milled and ported has performed as good as any of the 061, 062 or 882. David Visser wrote a book on SBC and head work that explains how to get the most out of these heads. As David says in his book "I don't have an opinion, I have a dyno." The Dyno don't lie.

    I have a set of 882s have a port and polish job on them with a set of flat tops and a moderate cam they work really well its around 380-420 crank hp and the things scream for what they are. I think they are excellent for a hot street mild strip engine on the cracking issue they really don't like to get hot but if your lucky they might not crack so just don't overheat them. just my 2 cents

      Yes the 041 heads flow very well as the are essentially as the 461 heads but have the accessory holes for running a more modern pulley system..You can enlarge the intake valve to I believe a max of 2.05 ..You can also do some porting but for me a port match works wonders as these heads flow well to begin with especially for the street..

    • @oneforliberty
      @oneforliberty 7 ปีที่แล้ว +3

      Well Joe I would have to ask what are your plans with the motor?? Porting and polishing is costly because of the amount of labor time and even worse if done by a sub-standard machine shop could cost you your heads ..Taking out too much material and getting into water jackets can make the heads worthless, so make sure the people doing the job have the experience and stand behind their work..
      Now if it was me and my only use for this motor was the street I would do a port match with the intake and select a good cam, intake , carb and headers..But if the goal is a all out killer race engine I would most likely invest in a set of over the top aftermarket aluminum heads and save or sell the 461's.. The 461's were designed as a great street head and can be improved on to a degree but really still just a great street head..

    I am surprised that the 5.0L/5.7L Vortec heads weren't mentioned in this video. They are a Gen I small block. Those are also a very good choice port design in those heads were based off of the port design in the Gen II LT1's. 1.94/1.50 valve size with a unique multi angle valve seat from factory. Stock vs stock the Vortec's flow more than the camel hump heads, already have the hardened valve seats for use with unleaded. However they do need a little work if you want to run a higher lift cam. They also have a fast burn style combustion chamber.

    041 was from 68-70 350 300 HP engine and were fitted with 1.94 in valves, 186 was specific to 302/350 LT1 and generally featured screw in studs and guide plates and 2.02 in valves. Both heads used 1.6 ex valves. As with everything in this era there were random variations that I can only attribute to using what was on hand to fill small gaps in production runs. We saw 041 heads machined for screw in studs and guide plates and 186 heads that were not. 186 for the most part had 2.02 intakes, 041 were again for the most part 1.94s Machining the 1.94 seat can quickly and easily be opened up to accept 2.02s. The 882 was the first real attempt at a lighter weight head and is also prone to cracking. I enjoyed your video. Good work.

    • @ayebee1207

      Sorry, Myvintageiron7512; I want to clear up your misconceived notions on firing orders.
      Just as Frank289100 -Troll, was wrong on firing orders, stating: LS-1 Chevy firing order was a ripoff from Ford's 351C.
      Now read on.......Ford's early 289 and 302Non H-O, as well as the following 255, 260, 352, 360, 390, 410, 427, 428, 429, 430, 460, 462, all have this firing order: 1-5-4-2-6-3-7-8.
      How Ford numbers their cylinders:Passenger side bank 1-2-3-4. Drivers side bank 5-6-7-8. So that means on this group of small blocks, big blocks and Y blocks, they all have same flaw of #7 and #8 cylinders[same bank] firing in succession. Detonation/pre-ignition potential.
      The 302 5.0 HO, the 351 C,M,W, Small and Big blocks and the newer 4.6 and 4.7's Firing order of: 1-3-7-2-6-5-4-8 have flaw of #6 and #5 cylinders on same bank firing in succession[Hot spot]
      Small block and big block 1st Gen Chevy's 1-8-4-3-6-5-7-2 Firing order means that cylinders #5 and # 7 fire in succession. Zora Arkus Duntov was aware in 1958 that #7 cylinder on any little Chevy always ran [Hot]Lean.. Some dual plane trickery helped.
      The Chevy LS-1 has firing order of: 1-8-7-2-6-5-4-3 No adjacent pair fire in succession.
      Better mixture distribution and better harmonics in the Intake tract. Less loads on rod and main bearings.
      In factory stock class in NHRA. Reverse cooling into the head[Legal- Mod] addressed some of the issues on #7 cylinder on 1st Gen Chevy. You have to run factory oem blank- Cam grind[Lift limit] per rules.
      If you just figured out, by what I have posted, that there maybe unlocked potential in any of the Ford or Chevy's listed above, with their cam sequence on factory index and you want to discuss options call your Cam guy. Custom grinds are stocked to address this issue. Intake and header changes are needed for changes in incoming and exiting flow.-Power lesson of the day.

      @silicon212 10 ปีที่แล้ว +2

      Aye Bee
      The 351x, 302 HO and mod motors have the exact same firing sequence as the LSx GM engines. The written order is different due to the cylinders being different, yet the sequence is exactly the same. The thing you write about 5-6 on the Ford engine you claim is not present on the GM, but it is. The ORDER does not show this, but the SEQUENCE does. 13726548 is the exact same sequence as 54318726 (same ORDER, same SEQUENCE, different NUMBERS). Note that 3-1 on the GM are subsequent firing - this is the exact same as 6-5 on the Ford.
      In other words, 18726543 is also 187265431872654318726543 ... get it?

      I don't dis agree with with what you said except for the (misconceived notions) part all I said was ford and Chevy firing orders are the same if u number the cylinders the same way, you didn't even address that! the 4/7 swap cam is no secret and the flaw in the Chevy and early Ford firing order is common knowledge I was just making the point that they are the same sequence because Mr. FORD RULES THE WORLD would have a spaz attack when he realized this is true

    @scottc0510 4 ปีที่แล้ว +2

    THANKS for all your very informative videos. I've enjoyed MANY of them.
    I think I have three good questions. Here's a little background before I ask them.
    I recently bought a 1991 (last year square body) 1/2 ton Chevy Suburban.with an amazingly straight body and good frame and suspension, etc., for what I think was a terrific price ($600)... I bought it KNOWINGLY with an apparent bad valve guide in the cylinder head for the #8 cylinder. It's leaking oil and fouls plugs often. The others all seem okay.
    This is an ANEMIC engine, especially in such a heavy truck on 32" tires with 3.08 gears, but it has (documented) approx 15k miles on a rebuild of the 700R4 trans AND transfer case.
    My plan fro the get-go has been to build something RELIABLE, with maybe 100 h.p more, and do some axle swaps (1-tons) with a front to rear spring swap, true dual exhausts (Flowmaster 40's), and 3.73 gears with at least a posi in the rear. I'm planning to rework an OEM engine harness.
    Within a month of buying the truck, I bought a VERY LOW MILEAGE (68k mi) 5.7 PORT INJECTION/throttle body engine from a parted out presumably 1995 Cadillac limousine. My research has led me to believe it's a 1st Gen LT1... 265 h.p. I saw a video of iyt running before pulled and saw the digital odometer confirming the mileage. It ran very smoothly and there was no check engine light on in the dash instrument video.
    I basically bought this engine actually sight unseen. The price sounded right for such a low-mileage engine. The downside- the guy who pulled the engine butchered the wiring harness and failed to get the ECM from the car before it went to the crusher.
    Question 1) How do I determine that what I have (engine going in) is indeed a Gen 1 LT1? "Sawtooth pattern on the heads? Existence of the Optispark system? Ansence of the middle two intake bolts on each side of the intake? Any cast numbers I should look for?
    Question 2) What/which ECM should I use?
    Question 3) Is there a cam you could recommend for good low to midrange HP and torque that would give a LITTLE lope but retain good streetability and off road torque/power? (I'm NOT looking for a beast- NOT a high revving engine)... Maybe a stage 2 RV cam?
    Thanks again for your great videos!!!

    • @Mike-yq7ce
      @Mike-yq7ce 3 ปีที่แล้ว

      You most likely picked up a GEN II engine. 1996 was the first year for the sawtooth heads. You'd probably be better off picking up a set of the 96 and up 5.7L Vortec heads you would also have to pick up a Vortec specific intake Edelbrock makes a TBI one for Vortec heads. Those heads alone are good for about 40 hp gain add a mild cam to the mix and that should wake your existing engine up along with switching the 3.08's to 3.73's. Would be way less headache than swapping in the Gen II. Another option would be to look for a 5.7L Vortec from a 1996 to 1998 Chevy truck, Tahoe, or Surburban along with getting the Vortec specific intake. The 5.0L/5.7L Vortec's are still a Gen I small block. The 5.7L's were factory rated at 250hp/ 330 torque with 9.5:1 compression. They can be easily made to make 400hp. Another benefit of finding that engine is in 1996 GM cast these blocks with higher nickel content and they have factory roller cam. Honestly I do not know why the Vortec heads weren't mentioned in this video. As they are better than any of the 76cc heads mentioned IMHO. The Vortec heads are basically Gen II LT1 heads that are for a Gen 1. The port design in the Vortecs were based off of the Gen II LT1 heads.

    The 882 arent so bad IMO, back in the mid to late 90s, i had a built .030 over 350cid 4bolt main, 4valve relief flat top piston engine, along with a combination of other performance enhancers(all motor, no spray) in a street/strip driven '75 chevelle and it helped produce consistant 14.40s @ 96mph in the 1/4mile. Now granted, for what im about to tell you would be considered a waste in yours as well as everyone elses oppinion and i am inclined to agree, but i had these same heads thoroughly checked, then ported and polished, rocker stud bosses milled for screw in studs, SS 1.94int/1.60exh valves along with new springs/locks/retainers and valve seals to use with a hydraulic flat tappet camshaft. Now dont be too harsh on me, it was my very 1st high performance engine build, so i experimented some with what i had atm and it appeared to have worked out for me in the end. But i did upgrade to much better aftermarket heads later on for a better performance to price ratio... rumor has it, even when using all the wrong parts, chevy engines still make great power. lol

    I'm an auto machinest of 38 years. The 041s were undercover beasts as they were not a true performance offering and as I recall were all 1.94s! You could pretty much port away or you can find a strip ready Crane reworked 292 turbo. They flow well and were go to heads for years and could turn the Rs on a 302. We used to try to finish them up a touch more for customers. Right through a water jacket! Glad the bowties came out! 882 are l82 trashers. I don't think you can touch the 186s as they cost too much unless you find molested 186s. As far as performance. You could do very well with the cheapo Chinese heads as long you get the vortec intake version of the heads. They are 195cc int and 76 exhausts 64-68cc chambers, so you do need a peppy cam. Just have someone who knows what he's doing go over them! They pretty much need a good cleanup as long as you get a good set. If you order a set and get tokyo crappos, send em back. Funny thing with BBC, you had the aluminum counterpart to get over the counter. E.g... The cast iron 840 had the 842 aluminum cousin. They then came out with the 077s. The nice thing with aluminum, you almost always could fix them, whether sbc or BBC. Funny story is a young kid who wouldn't listen to me about compression. He came in with a set of 267cid heads and thought he would have a compression monster on a 400sbc. I wouldn't even drill the steam holes for him. Kid drilled them out himself then had a meltdown! I warned him about the valves and shroulding not being able to get rid of the heat

But by the time you angle mill, cut new guides, seats, screw in studs, port/polish heads, cut the spring pads your Going to have more money in then a new set of Dart or Airflow AER heads or even Brzezinski heads. And the new castings an be replaced and easy to find. Old castings crack easy or remember they might have set in a junkyard with water or weak antifreeze in and will need to be checked for cracks. Don't put pins in studs they will break. Buy new and you'll get your money's worth. It all depends what your running the motor in race spec, street, hotrod

    Seen a 396 bbc build you did. You talked about how wd40 is recommended for ring seating. I built a 40 over large journal 327 with true forged ft pistons, moly coated top ring and iron for 2nd. I used assembly lube on my rist pin area and ofcourse the r&b bearings but i only sprayed wd40 on my cylinders and the pistons and rings during assembly. No oil coating of the the cylinder or pistons and rings. That was maybe 4000 miles ago. 81 Malibu 410 posi, built turbo 350 and i run it hard. It does not smoke ever and it does not use oil. I know of some builds that didn't seat in as good as mine and i believe it's because the wd40 isn't as slick or oily and allows for proper seating. I think you said that's actually what it does and i can confirm it most definitely does. Just did a 60 over steoker same way but haven't had time to drive it yet, only break in the old Elgin 3030 solid that i put in it with a shaved set of 041x haeds. Should've bought name brand aluminum heads because i ended up with probably 850.00 in setting up mine.

I have a nice 1966 /327 Small journal steel crank & rod short block doing nothing that I am going to bore it .030 with new cast flat top pistons and molly rings. I want this 327 to run on 86 octane pump gas so I need 76cc chambers and hardened seats for a daily driver. True you can install hardened seats in any of them, but lets assume we are building this on a tight budget, and are looking for the best factory head to wind up with around 9.0 compression to run on anything the stations are selling as gas. For this combo with a stock lift & der. cam I think the best head might be the 882 heads ( if I can find a pair not cracked )for this 327 in my daily.

He has another motor he started building and it has been bored 30 over with new pistons installed, stock crank. He has an after market set of 906 vortex heads he wants to sell with the motor. Firstly, are those heads going to be adequate for the block and the cam is an edelbrok that produces 245ft lbs of torque.

    I had good success with 305 4 barrel heads on 350's. But I've found most if not all factory chev heads were mass produced with no attention to casting detail. Without a flow bench leave the runner alone but hog out the valve pocket and smooth out the pocket (think water flowing) the larger volume in the pocket helps draw air down the runner and is helped by the removal of sharp edges. All you need is a die grinders and a steady hand. Take a junk head and see how much can be removed first if uncertain.

About once a year he'd blow it up and just move his heads over to another 350.

    Very good and informative piece on s.b.c heads. I have a pair of 041's that were manufactured in 1970. These heads have been sitting in my garage on a shelf for nearly 40 years now. One of these days I will dig them out and install them on a mildly cammed 350 4 bolt. Keep up the good work!

    great explanation. thanks! at a swap meet, i found a set of 461 heads with 1.94" intake valves i'm about to put on my '65 elcamino (gotta deadline of 5 weeks to complete at this point for a work related car show). it's a 283 with flat top pistons. i'm running an electric fan, and power nothing, manual steering, no ac etc, so only the alternator is run off a belt, and the alternator bracket is bolted to the exhaust bolts on cyl 1, so i lucked out there since these 461's have no accessory mounts. what do you think my comp ratio is going to be? general numbers are ok, just hoping to get close to the 10 range or above hopefully. going to run and edelbrock airgap dual plane, edelbrock 600 cfm carb and long tube headers. not going to be a beast, just a good little motor with decent spunk in my 3200 lb '65. going to watch some of your other vids now. thanks! sub'd!

    • @Myvintageiron7512
      @Myvintageiron7512  11 ปีที่แล้ว

      with fully ported 882's you will see 25 to 30 HP gain that's about it if you can do it yourself and have the time I'd say yes I wouldn't pay to have it done also it's important to remember head porting is not a matter of just hogging out ports it has to be done correctly It's easy to destroy the flow characteristics of a port if you take a little material out in the wrong spot.

    • @tlbawheelspin630

    I had a 1968 Camaro with a different motor, a 350. I took the heads to a machine shop and he said they needed tons of work but he had some heads that were all set to go. So, I bought the heads from him. Next, he told me a kid at NAPA wanted to buy my old heads for $35 or something like that. Of course, being a poor kid myself, I sold them to the guy. I wonder what heads I had... obviously, good ones. This was back in 1983.

      I did the same thing when I was young. They were factory 'J' code 4V hi comp. heads off my 68 Mustang. Napa machine shop said they were junk and worthless and asked me if I wanted them back. Not knowing any better, I let them have them for nothing. What a bunch of thieves. I bet they did this all the time. I bought a set of plain 289 heads and got the motor going with them and then I sold my FASTBACK for $750 and thought I did well...

    • @GnarshredProductions
      @GnarshredProductions 6 ปีที่แล้ว

      @Hugh O'Brien vortec head should be a much better head due to the port being taller the airflow is more direct to the valve it doesn't have to turn as much. Same reason why the LS heads flow so much better. It's not all about the size of the port but also the shape and how direct the flow path is.

    You do offer a lot of good advice, but there are a few things you missed. I'm a Machinist (but in Canada) so we have a few different casting numbers. 64cc with bolt holes, 370 and 492, 69-70.They both had mini camel hump castings on them. Other early camel humps were 462 and 291 Also, according to NHRA the 305 heads have the same intake and exhaust ports as a 350 head, AND, it's not hard to install a 1.94 intake valve in a 305 head.

      The only heads here with mini hump castings were the 186 heads with the accessory bolt holes , as my 462's and 291's had the big humps on them , and according to Brzezinski racing head service the 291' s are some of the later FI heads castings that are actually better because of improvements that they did when they were made back in the late 60s early 70s
