there are plenty of cam manufacturers working on the LS3 and L99 that will be able to tell you if you need to change your pistons, however, unless you go with a pure donkey-di@# race cam, you shouldnt have a problem with valve/piston clearance.
that being said, the L99 and its VVT does require a little bit of finesse with the cams available for it as well as the tuning of the VVT to eliminate valve/piston contact.
but I wouldnt worry about the clearance unless you are going with a truly radical cam setup.
