Anyone CC'd the Combustion Chambers on EQ Magnum Heads

Thought these EQ cylinder heads were 62 cc in the combustion chamber from the factory.
I cc'd the heads today that Brian at IMM did for me and the cc's averaged 65.4 cc's with the 2.02 valves installed.
I know there is factory tolerance but is this normal?

You are correct in thinking they were supposed to be 62cc even with Hughes 2.02 valve.
I copied and pasted this right off their website.
