I have a 76 sbc with RV cam, performer intake and carb.This motor new had a low CR,so looking to vortec style heads, but would like to keep my intake.I think Pro Comp aluminum heads will take my intake.Are these heads any good? I don't really care if it's aluminum,so if you can recommend a head,please do.From what I read today a dif cam might be better too.I won't be rev' g over 4000, just want a driver motor. Cisco.

Don't waste your money. You get what you pay for. If your just wanting a basic head to up the compression and give it more breatheable power upstairs then you the basic world S/R Torquer heads are for you. These are stock replacement heads that breathe better and have a smaller chamber to raise the compression ratio, you'll want to use them with a thin head gasket. Even if you install them and get it dialed in correctly regardless of whats been said it will still be sluggish until you get some gears in it.
