- I HAVE A COUPLE OF TESTS IN MIND FOR THE AFR 302/351W FORD HEADS I GOT. I NEED TO TEST P-V WITH THE BIG VALVES AND COMPARE TO GT-40 HEADS-THEY SHOULD ALSO GO ON A JUNKYARD 351W

I used the 185 enforcer heads on my 395w 9.7cr build with a tfs stage 2 cam and a edelbrock rpm air gap topped off with a 750 vacuum secondary. Fun combo in a 3000lbs car. I used a hp calculator it estimates 450hp at 5500.
Would love to see you go through all the combos with the 351!!!
There are 2 versions of this head which probably caused the flow number confusion. They sell a small valve and a large valve version.
I had the AFR 165 on my SBE 302 small turbo 5-speed Fox body and those heads made plenty of power with the turbo I was 500 to the wheels on 8 lb of boost AFR makes straight heads I now have 225s on a 375 stroker in the car love AFR heads
Is it still running?
Just started watching but have these heads on my 357. Out of the box heads and tfs stage 2 cam made 700+ whp on a dynocom with an eddy brake on 11psi boost pte 7675
Thx for your knowledge 💪🏽
I had to notch my piston on my 87 GT short block for the Promaxx 180 heads 2.02 1.60 I just used a drimel and used grease to keep the shavings from flying everywhere. Turned out good. I’ve got a video on it somewhere in my play list
I like to use a old valve. Glue some sand paper to the bottom and roll it up the sides slightly and put the valve in the head and set the head on the block with two bolt in it. Then get a drill and push down on it and let the sand paper do the job. I fly cut my pistons on my ls1 In about a hour or so. And it looked professional lol
@@Smxsucks awesome!!! I’ve heard of that method also. The last ones I did I used a old valve and just cut teeth on them. Worked really good also.
What cam did you use? Im looking at the same heads for my 90 351 and a Lunati efi272hr roller cam. The lift and duration is pretty mild so am hoping it clears but could probably clearance the stock pistons.
@@supersportimpalass I used the E303 cam. The 351 pistons should be good but definitely check.
Was there a follow up to this video that says whether or not the 274hr cam works with these heads and a sbe 5.0?
Im building 393w with enforcer afr 274xe its for 69 fb mustang tkx 5 speeds trans and sniper i hope it work good with the enforcers
New Ultraman movie?! We grew up on those!
The renegade head is the cnc ported one. The enforcer is as cast.
Hi Richard, love all your stuff especially about small block fords splitting. I would like to see how long an internally balanced, well tuned 347 would last. I think I am not going to pay for a Dart block and just have my 90 block property stroker and balanced. Then not rev over 6500 and see what happens.
that should last a really long time. im moving in that direction with these enforcers in most likely and a forged eagle rotating assembly and a howards 235/243 .565/.565 rattler cam it'll be with my OG 1979 block retro roller
I have personally seen them split but they normally split due to boost and too much torque
With DSS pistons,.027 head gasket, degreed in at 108, I had .093 thou on intake and .290 on the exhaust. Pistons .011 in the hole.
This is the xe274hr
DID THEY HAVE VALVE RELIEFS?
It hit right on the eyebrow about a 1/16th on my 95 sn95
Won't notching pistons in the engine have an adverse affect the balance ? Just being curious ! Thank You for any information that You can share I would greatly appreciate it ! 🇺🇸🇵🇷🦊👍
not if you do them all the same
What do you think about Tfs stage 5 cam with promaxx project x 190’s. 331. Scat crank rods. Icon forged. 11.5 comp. Any ideas
NEVER TRIED A STAGE 5
Richard, I ran the silver state a few times when you were up there, still have thew same Mustang. Super charged 331 with TFS Street Heat heads 410 hp rear wheels. What do thing if these heads .
they r good
Will there be a dyno run of the SBF AFR 185 Enforcer Heads soon on a 351 windsor?
I should
I have a ford 302 with stock pistons i am using a flat tappet camshaft. would the AFR1351 work ? If not any recommendations
what cam?
Did a 351 w and a 185 afr race heads .530 hd cam made 492 hp and 500 torque
Naturally Aspirated?👀👀
@@colewixson3642 yeah and i believe it renegade are pretty good heads. the 11r TF 190s are capable of it too
Here's a question, knowing that these are knock off Dart heads and that many companies sell this casing under their brand.and that the majority of the issues people have with them is the valvetrain not being up to par. is it possible to buy a set of bare castings and knock out the 11/32 valve guides and install 8mm stuff such as what afr does with them, or are the holes drilled out too large already?
AFR HEADS ARE A KNOCK OFF OF DART-SEEMS UNLIKELY
@Richard Holdener Only talking about the Enforcer line of heads, the even admit it on their web page, also Eric Weingartner does a thorough direction of several heads

@@richardholdener1727 Your kidding right? The enforcer sbf casting is a clone of a old ported dart pro 1 head.. Blue print brought that casting to market with Chinese production over a decade ago... Hell Dart is selling a Chinese clone of an afr 205 under there shp line now. All the Chinese sourced heads are clones of an American made heads and now the big name are even selling them. Replacing blueprint heads with the enforcers... Its the same casting with different valve train.
If you get a 351W, build it like the 410 that David has in his Disgustang.
Have you ever experimented with world windsor sr iron heads?
yes-but no video on those
Test the enforcers please
Whos head did Promaxx copy for their SBF 185cc Head?
Edelbrock for the series 1, sve was the same casting from Steve sun engines, different variations on the port work though but same base casting..... The 210 &185 x are AFR clones, same casting as floteks hammer 205 and darts shp line has both the edelbrock 175 and afr 205 sbf clones now... Welcome to investment firms owning the industry..
@@nothanks81 If I'm understanding you correctly; the ProMaxx 185 SBF head is a AFR clone, but used to be an Edelbrock clone ?
@@chestrockwell8328 They have two different castings for sbf currently with many port size options, only the project x heads are Afr clones, the rest are based on edelbock copy. These are permanent mold castings, all they are doing is changing the runner cores for as cast size. All the Chinese heads are tweaked American heads someone had a foundry there reverse engineer from a cleaned up head some one brought them. Steven sun cast the edelbrock clones, I haven't looked into who did the afr copies but promaxx isn't the only one selling them... Hell way back before it got bought and renamed Promaxx they had a really bad afr copy of first gen heads called the Patriot head but quality has improved greatly over the years on the cheaper China stuff. And pro comp is a piss poor Vic Jr copy if your wondering...
@@chestrockwell8328 ALLEGEDLY the project X's promaxx are AFR clones according to eric weingartner
Are NKB heads a version of this or copy of dart
SIMIALR TO AFR I BELIEVE
afr has the superior valve train. they use the same components in their renegade version.
Intake was a air gap on the 351 form the comment
Hey Richard have y’all checked PVC on these heads on a 302 with a stock bottoms end?
not yet
I had ptv issues with this setup. Shop had to fly cut. I also had to get tall valve covers - which then necessitated a 1” spacer.
@@steelerpen87 interesting! I did checked pvc twice and it was good. Idk if it matters or not I have a 94 short block with stock pistons (I think they are the same as 87-93 just not forged). I’m using stock valve covers with 1.6 rockers with no issues so far with a f cam.
@@chasecary92 Interesting. Shop had me up to show. They tested with clay and mechanically. They had to shave the relief eyebrow out a bit to accept the larger intake valve.
I have a stock 302 bottom in an 1989 foxbody vert. Trick flow stage 1 cam. 1.6 scorpion rockers.
Same thing with valve covers. I had cobras. They tried removing the baffles and grinding inside to make them work - no luck.
Shop explained it’s a case by case in terms of clearance issues- lots of variables that make car to car comparisons difficult.
End of the day. I’m happy. Noticeable seat of the pants more power and torque.
Have you reviewed these yet?
not yet
Do you have an email I can reach you at....I have an idea for the 90s 5.0 efi....maybe you have the parts to set up to test my idea
ASK AWAY-OR COME JOIN THE LIVE FEED NIGHTLY AT 7 PM PST
@@richardholdener1727 i would like to get a SBF AIR GAP INTAKE and drill out the bosses to accept the factory fuel rail and injectors and also get a holley efi part# 300-240 and bolt it to the intake or something similar and then bolt the factory 65mm throttle body to that....does that paint a pretty good picture of the set up. Basically replacing the foxbody lower and upper intake.
Comp can regrind that xam
Moroboshi...
bullshit. im the biggest Ultra man fan in the world. i am. period end of story
NICE TRY
