Default what heads?

I'm looking into getting a set of heads to go along with my MS4 cam in a 02 Z06.

What is the differance between Ls6, L92, Ls7, 6.0, and 5.3l heads???? What would be the best set of heads for my setup at a decent price. Not looking to go nuts and get AFR's, even though I know they are really good. Is the price in heads really worth the extra bit of hp? What type of hp gain would I get with aftermarket heads over the stock LS6 heads?

Was looking at these

But with the ls1/ls6 block you are not going to be ablt to run l92, or ls7 heads because they are a 4" bore head. As far as ms4 cam is concerned, i dont think it would work with 5.3's without flycutting and the ls6 and 6.0 heads are the same but 6.0 heads will lower compression unless they are milled. I would seay your best bet it to go with a cnc'd ls6 head, call tsp and they will get you the best heads to match their ms4 cam. Tim
