You are 100% correct. I *assumed* a cylindrical combustion chamber. I do not have the combustion chamber geometry. I do have a 3d laser scanner, so if I really cared, I could get accurate data. I was trying to get a feel of the "order of magnitude" of compression ratio change with a 0.010" milled head. I now know it is on the order of .2 gain from 9.0:1.
I will post the corrected calculations below. Taking this into account:
sv = stroke volume
nv = non "stroke volume" volume = combustion chamber volume + head gasket thickness volume + others
compression ratio = cr = (nv+sv)/nv
Therefore nv = sv/(cr-1)
Thanks for finding the error.
