Thanks it is a 249HP crate, Touque 304@3500RPM,4bolt 2pc.main 4"bore,3.480strock,cast iron 76cc194-1.5 heads,cam is .390/.410lift.
Just want to know if changing the heads from 76cc to 67cc will work and what would the compression ratio be? It is 8.5:1 now. Also the valves are 2.02 and 1.6 in the smaller 67cc heads.....Thanks for your help....Jim
