You would be better off getting aftermarket ported heads (larger flow and bigger valves) or have your current heads ported. The main difference between the LS3 and L99 is lifters, cam and variable valve timing I believe.

Ls3 has hollow intake valves, significant valve train weight benefit. You could just buy those and throw them in your heads.

My car had some blots on it too but I did a good thorough detail and they went away.
