milling ls3 heads

hey guys im in a process of doing a cam swap on my 2010 l99 motor. Im deleting dod/afm and vvt. Cam im going with is patrick g stage 1 ls3 cam (225/232 .629/.615 114). btr ls9 gasket, morel 7717 lifters, 7.400 pushrods. Im gonna send my heads out to get them decked, however im thinking of milling them for bump of compression. I was wondering how much milling would be optimal without changing my pushrods. safe to run on pump gas

Change pushrods. It will be worth it. Run Cometic .040 gaskets and mill .015 to .030. it will be worth it. You'll later kick yourself for not spending extra. And if you decide to later, you spend more on labor and time. Do it right the first time
