Can anyone tell me how many thousandths have to be milled off the 5.3L 706 casting heads to decrease my combustion chamber volume 3cc's? I'm going to mill them and want to get an idea of how many cc's the volume decreases in relationship to the amount of material removed. I just bought them and requested 59cc combustion chambers but when I cc'ed them they are 62cc's.

It's about 0.006 for every cc, so you would have to take some 0.015-0.020 off the heads.
