Heads and cam

I got a 2007 SIERRA 5.3L (New body) FLex fuel. and i got a set of heads and cam off a 2000 camaro SS. Would I get any benefit on swaping cam and head or just head or notting, just port and polish the OEM heads.

what is the casting #'s on the heads. probably a waste of time with zero gains.

your 5.3 has LS6 heads so that would not be smart to change the heads. the ls1 cam is probably a tad bigger but not worth the effort of putting it in.
