thanks for the information,just trying to get rough estimate on compression ratio on my stock 360 . heads have been milled .020 found compression calculator on other abody site. Found head gasket thickness make a big difference going from thick to thin gaskets.
Thanks again Bob

FWIW, the bore in head gaskets varies quite a bit from just a few thousands bigger than an 0.060 over bore to over 100 thousands. That will make quite a difference in the compression too. The Fel-Pro head gasket I used had a 4.180 bore.
