Compression Ratio for Milled heads Ok, not too long ago I seen a post that had info on "if you mill this xxxxmuch you get a compression ratio of XXX...cant find it anymore. I tried a search no luck.
Looking at 5.7L Heads milled about .025/.030/.035 and also what size pushrods to use for them with after market cam, and stock head gaskets.
Thank you.

I asked this question a while back...look up Tin Indian , he came up with a mathematical model for the effect of chamber volume on compression ratio...you'll need to know the combustion chamber volume in CCs...my LS6 heads milled .030 came out to be approx 10.9 to 1. FWIW, MTI says you get .5 increase in compression for .030 milling.
