Anyone know anything about these heads? I'm a little skeptical on the "512hp @ 7500" on a stock 302 with a cam and intake. I sure do hope its true though lol. and if its true are they worth the $2500? is there an AFR or TFS head that will make those kinds of numbers?

They aren't worth the time/money. Especially on a 302. They have unique valve arrangements that also cost more. If you want a great street/strip head go with the new R11 TFS 205cc heads. They even give a little extra room for ptv clearance so you can run a little more cam. IMO they are the best 2k or under head on the market(have 2.08x1.60valves,PAC springs,titanium locks-retainers,etc) they support up to 650hp n/a or 1000hp forced induction in the right motor

I'll look at those? do you have any clue what numbers they'll make with the similar set up? (cam, intake, headers)

Well basically any 200+cc head is capable of going over 1000 hp. Just use more boost lol. I think they can double up the n/a numbers with the right setup

I can't remember exactly but I think the p heads need custom valvetrain pieces,otb intakes need to be ported to match(not positive on this). The new 11r tfs heads use traditional roller rockers,intake,exhaust etc. and are cheaper. With a stock 5.0 they both are overkill. Will one make more power than another? Possibly.

I like the p38 heads. They are outside of the box and thinking a little different. I think they are more at home on a large 400+ cubic inch motor though. They probably won't get anything done that some of the other mentioned heads can't.

Don't see an NA motor getting near 1000 with high ports . You will need SC1 D3 blue thunders or that type of head

The Kaase head is a great piece. If you were looking to buy a cylinder head that you could grow into it would be an option. The valvetrain geometry is a little goofy but people make OTS rockers for them and it isnt an issue.

I looked into them but ultimately i thought high ports were a better choice for my money.
