Default Re: combustion chamber volume

In the shop I worked at we had a factor written down for almost all common Chevy heads for milling. I milled and cc'ed every head you could think of for over 10 years. An old high compression head like a 461 was about .0065" per cc. A newer style open chamber head like a 441 was around .0058". Bigger chamber area/smaller factor.....smaller chamber area/bigger factor...

Those numbers are from memory......it's been many years since I did that work everyday....
