not really, if you really want better heads on your 5.3, go find some 243 or 799 casting heads they are identical to ls6 heads the ones on the trucks have different valves but still perform great. Sell the ls2 heads and cam, you can't use that anyway. find a used Ls6 cam and springs and you will have a good running low budget 5.3 that can make 380 hp

ahhh yes good point, I was pretty sure the 6.0 Ls2 had bigger chambers I should have done my homework.... ok well if he has dished pistons keep the 243/799 heads and put a turbo on it to compensate for the loss in compression...lol
