This is good, now let's turn the coin...

I'm looking at a cam swap and a friend of mine says' to shave the heads and bump up the CR while I'm at it!

On a stock 02 LS1what is safe? How much can I shave off without worrying about valve piston interference?

How much can I bump up the CR and still run on 91 octane pump gas without problems?
