Just to clarify that although Adder is once again being attentive and helpful, his reply is an estimate. Specific measurements like combustion chamber \ piston volume with the gasket anddeckheight are needed as well as standard ones like bore and stroke. Hell, I could be wrong. Maybe Adder knows a 5.0 that well.......

whoops... scratch that... my reasoning was wrong.... its .005 comes out to roughly 1cc taken off the heads combustion chamber

however, it still shoudl give him a ~58cc chamber which is ~9.5:1 compressionr atio

So the stock head is 64cc's? I thought I read that a stock E7TE is 61.5..correct me if I am wrong.

Also, is the .005 to 1cc common on all heads or just these ones specific?

I realize there is much more to it, but basically I just wanted to know what my CC's are.
