Question about Milled heads? just bought a set of 317 heads but there milled .0015 what will that do to my compression ratio. Also what thickness heads gaskets should I buy, to either lower the comp more or make it even from the milled heads. Thanks

I am not sure but I am guessing that your heads were milled .015 not .0015. that would be like wiping the entire head with a piece of sandpaper once. The gaskets for a .015 mill could make up the difference but what is the chamber size on the heads? You are probably going to find that .015 won't make more that .05 to .1 compression ratio difference once you do the math.

well the guy said he just had the heads cleaned up and checked out. And he wrote .0015 so I'm not sure. heads are 317 so the chamber size is 72 or 74cc I think
