Default Re: pro comp heads

1968BM, I would NOT run Pro Comp ANYTHING, let alone heads. FYI for what it's worth, I have a .030 427 with closed chamber oval heads. Nothing fancy or special. Really just a L-88 with better solid NOT roller cam, ported oval port heads, holley intake. Street car @ 3500 lbs HAS run 10.40's in a '69 Nova. Hadmore in it but got booted for no roll bar.

Now we have another 427 .030 over, 12.5 to 1 with roller came, ported sq port heads on a factory dual plane intake that makes north of 700Hp with the roundy-round cam. Car runs 500 mile endurance races.

Just use the factory heads, nice RPM air-gap intake with a mild cam and you'll be better off.
