I think it was JohnP that posted it. Anyways we had a breakdown of compression ratios to increments removed from the head. Does anyone still have that to post as a sticky?

JonsZX2sr posted a list of material to be milled for different compression ratios . I use 0.030" just to clean and level the surface . For a 10.5:1 compression I use 0.070" , this brings it to almost a full point over stock . Remember the stock head gaskets run from 0.030" to 0.050" .
