Took .040...flat cut. Iirc..about 5.5 thousandths per cc when flat cut. Put mine at 58cc from 65cc.

Thanks......

I bought mine milled at .042" I have yet to get a diagnostic camera in there to see if I have any valve marks on the pistons. I am planning on switching to 243/799 heads at some point.
