CC cylinder head combustion chamber

[dwg86]

What is the maximum alowable difference in combustion chambers when checking the CC's?

Stockers often vary by several CC's.

We just worked over a set of performance heads in the shop and brought them to within less than a tenth (less than we could really measure accuratley) across all chambers.

Depends on how picky do you want to get.
