Cylinder Heads
460 Heads, larger or smaller on combustion chamber to get higher compression . My thought was 75.8 cc is better than 91.4 cc for more compression, Some people say iam not right on this what your opinion

He wasn't asking what was better, just what would be a higher compression.

If you have a 73 and later motor, the higher compression heads will wake up your motor. If you run the high compression heads and have flattop pistons(early 460s), you will have to run premium fuel, and its not advisable in a truck you do alot of hauling with.
