HI Paul,
41 cc's seems a little small for a stock head. I have some scratch notes around
when I did mine. It was 44.5 cc before re-shaping and 46.0 cc after re-shaping.
I then had 40 thou shaved to get to 43.5 cc which should get me to just over 9:1
compression ratio when I change to flat top pistons.
