Would I get a higher compression ratio with my 460 If I were to change out the pistons or the heads? If I ran a 95cc head with a high compression piston, or a 75/72cc heads with a stock piston? The high compression piston Im looking at have a head volume of +4.20 and a compression hieght of 1.752. The block will be milled and squared up, same head gaskets for either, stock rotating assembly. Im not sure of how to crunch all the numbers to get cr, thanks In advance.
