Does anyone know how much milling LS1 heads .030 will bump compression. If I'm still running stock pistons on my 99Z what would the compression become?

10:8:1 and P/v clearance will not be an issue unless you get into some huge cams like the gx5-3 or something like a T-rex cam. I ran a 224 cam with .030 milled and had plenty of space left. This is all basic ls1 stuff? Use the search function and you will find hundreds of posts.
