The normal answer you will get is:
1: Not enough info, 2: buy an over priced set of aluminum heads just to drive on the street and 3: the same ole same ole Comp cam 268 extreme cam. Oh yea one more thing, the favorite thing is 4: "ditch the Holley and run a quadrajet" that you have to send off and get rebult 10xs and still runs like a Voltswagon!
I say Dart Iron Eagles with big valves,480/280 Magnum Comp Cam and no less than a 750 DP Holley, 3500 stall.

No, I'm running 64 CC Dart Iron Eagle Platinum Cylinder Heads and flat tops with no problem. I run 91 octane.

9.75 C/R with Dart 72cc Heads and a .039" Gasket. The 64cc versions will bump you up to 10.6 C/R minimum. Match the cam to the C/R and you will be fine.
