Default compression q?

I recently bought used Trick flow 215 heads for my ls1...

the guy didnt know if they were milled but would get back to me on it.. with the heads and cam that it came with he said he was at 11.5-1 compression.

I have -2cc valve reliefs on my engine and wanted to run this head and the cam on my engine but with .040 cometic gaskets..

my question is what cc if you had to guess (before i check during the build) the original owner had them milled to have 11.5-1 compression on stock GM mls gaskets? my guess was 59cc

the cam in question is mid 230's in duration and low .600-inch lift range with a 114 lsa....
