what's difference 4.8 / 5.3 heads??

Any info would be nice. Just purchased a 5.3 and was wondering any other differences in the engines as well.

I believe the only differences are the 5.3 pistons form a cup at the top, while the 4.8 pistons are flat and the 5.3 has a longer stroke, someone please correct me if im wrong.
