alright, what could i do to the heads, or what heads can i put on it?
There are many things you can do. What are your goals? Whats your budget?

Budget some time doing some research too...

i know what i can do to a 5.3l, thats my goal is a 5.3. but if i happen to come across a 4.8, i'll get it. i have a couple of books on the 3rd gen motors, but the authors really don't say much about the lil 4.8. i could get a 5.3l, an ls6 cam and get in the upper 300s as far as hp, and have plenty of torque...but the 4.8l doesn't seem as simple..

anything you can do to the 5.3 you can do to the 4.8. it has the same heads and bore. I think it was gm tech did a test on the ls6 cam in the 4.8 5.3 and 6.0 the cam with a tune gave the 4.8 about a 30hp increase.

You cant put L92 heads on anything that has a 4.0" bore (6.0Ls) or smaller. They wont fit on 5.3Ls.

don't forget to change your pushrods to match the cam.

Go a step further, change you pushrods because the stock ones bend. I had a new set of Comp Cams .105" wall pushrods in my truck within a week of having it.
