Trick Flow small block heads

Has anyone here verified the combustion chamber volume of their Trick Flow small block heads?

I am asking because I am estimating compression ratios based on specifications they list, but I don't remember seeing anyone say they specifically checked or verified the combustion chamber size. I assume it will be pretty darn close to the advertised specification of 60cc since the chambers are CNC profiled, but just looking for actual verification.

BTTT. Interested in this info as well. Have not read through all 42 pages of this thread but what kind of compression ratios are people getting with these? Inquiring minds ant to know.
