It will up the compression if your current heads aren't milled, but I can't say if they will give you any power or not. You will most likely have to flycut the pistons with a t-rex.

you're going to have to do some serious fly cutting with that cam, and 5.3 heads WILL up the compression to ~11:1. read about PRC's 5.3's on TSP's website....
