Default Need some insight on head/cam combo

Lookin thru some post on here for the right H/C package. Right now all i have are LT's with TSP duals, LID, K/N filter, VIG stall, 9 inch with 4.11 gears. Wanting to stay with the stock bottom half for now, and do not want to fly cut my pistons due to nitrous. If i went with the PRC 2.5 5.3 heads and a MS3 cam, later when i do decide to build a short block what is the most cubes you can go on the 5.3 heads?

Or would i be better off with the LS6 heads from TSP? What are the differences between the stage 1 LS6 and the stage 2 LS6 heads? Mt thoughts of short blocks down the road where one of these a 383 or 426.

This will be a weekend street/strip car. Goals in the future are to be a high to mid 10's on motor then spray 175 shot.

Why not the LS6 heads? You probably shouldn't run the 5.3's on anything bigger than a 6.0l. I am not sure if you could or not, but I do not see many people using a 5.3 on anything other than a stock 346 or forged high CR 347.
