head milling on a LS2 Would it be beneficial to mill the heads of a stock 05 GTO LS2. I was wondering if it would help the quench area and up the compression alittle bit but I am worried about piston to valve clearance. I also want to be able to run 94 octane safely

Just switch to a Cometic .030 and see how it does. Stocker is around .05something.
My buddy runs a milled head and .030s with a .224 but its pretty tight for my liking.
