Combustion chamber volume
Maybe I am missing something obvious, but why are combustion chamber volumes reported as a range? For instance Steve Christ reports the D2 heads as having a 68.1-71.1 cc chamber. Is this just the amount of variation among different castings?

The part that threw me off is that Steve Christ even reports about 3 cc of variation even with machined heads? I would have figured machined heads would be real consistent. I guess machined chambers only remove the hot spots not the variation in volume.
