I have a pair of Indy 440-1 heads that I bought used last year that needed fixing, I had them fixed and I CC both of them today. One is between 51.8 to 52.7 CC on all four chambers and the other one is between 58.2 CC to 58.8 CC, how many thousands per CC do I need to tell the machine shop to cut the large one to match the smaller one help
Thanks in advance for the help up bow
