LS6 cam would be a DISASTER in a 5.3 truck.
It's not the right thing for a small motor in a heavy (about 6000 lbs: nearly TWICE the weight of the vehicles the LS6 came in) with TERRIBLE gears (remember, not only the gears themselves, but also tire size, go into this).
It would be OK if your 5.3 was going into a Miata or some such. Total mismatch for a truck however.
I doubt you'll even be able to tell any difference between what you have and the LH9. That will most likely turn out to be a waste of time.
One of the 2 choices you get with stock cams: (a) a complete waste of time, or (b) a disaster. Don't make either mistake.

If you change your mind and don't mind deleting VVT, the L33 camshaft is the non-AFM, non-VVT, with the same grind used on the 2007-2009 LC9 engines. It is single pattern camshaft and runs real good.
