My heads are overhauled with new 2.02 and 1.60 valves with screw in studs. The combustion area is calculated to be 64.4 cc's. Hydrolic lifters.
The machine shop says to use a head gasket with a compression of .35 to achieve a compression of 10.1 to 10.5. On another forum they say that I'm leaving a lot of HP on the table with the cam selected.
Any help apreciated ! I will be assembly of the heads and components starting next week !
Here are the specs for the block and cam below. Thx VetteRed
