You only fool yourself into thinking how easy it is. You buy a $500 head and you get a $500 head. Everybody wants the most HP for the least amount $$$. Super Stealth's 100-150 HP over regular Stealth heads without a major head mod like Victor heads over RPM's? REALLY??? !~! Like I said, you buy a $500 head, you get a $500 head... nothing more nothing less. Snap your neck, mega G-force launch, is all I want!

It will have a hydro flat tappet cam 9.5 to 1 and I expect 550-570 hp @ 5300rpm. J.Rob Just saw this post and the 512 wound up making a whopping 523 hp and 583 ft.lbs. Yeah--I thought that was terrible and it is, although I think the cam and low compression has a major role in that. At least the 65 year old dude that owns it thinks its awesome. I have built '452 headed 451's that exceeed that with not much work at all. IF you just have to have aluminum heads then go for it, if you want to go fast then talk to somebody that knows.
