Default Rebuilding 03 5.3L Heads

Does anyone here think that just upgrading the stock heads that they could handle a mild to moderate street cam..im talking push rods, bee hive valve springs, aluminum rocker arms, i know that its a lot of crap to be messing with but im on a budget and doing all this is still going to save me a few hundred dollars. Just a thought, i guess im gonna do it unless someone has any other thoughts. Thanks, Devin.

all i know is that if you radically increase cc chamber pressure, it'll start blowing through piston rings.
