LM7 Turbo Guys: Talk to me about 10:1, slight mill, thinner headgaskets
So I've got a bone stock LM7 motor and the heads are coming tomorrow off for lifters and cam in preparation for the turbo. I plan to have a valve job and guides done on them at the same time, but I'm wondering about doing a mill or using a thinner headgasket to bring compression up to 10:1. Has anyone done this and what was your method?

What headgaskets should I run? I have LS9 gaskets but the bore size is way larger on the LS9 so I think there are more ideal gaskets out there. I also have 5.3 GM replacement gaskets (same as LS1 I believe).
