L92 vs Ls7

Ok guys, I am shipping my block and pistons out next week to get my shortblock built. Finally getting started on my own private monster
. My question is this: I only want to spend about 3K on heads. Would I be better off going with a set of basically stock LS7 heads, maybe some exhaust porting and milling, or go with a set of fully ported L92's? With a chamber size in the mid 60's and a .040 gasket I should end up with a 11.5~ 12-1 scr. My goals for the motor are 600 rwhp. And no I am not just looking for a Dyno queen, however that is what I need to run the times I want at the track. I am looking to get into the 9's on a 150 wet shot. The reason I say wet is 99% of the time I will be running with no bottle and I don't want to be running around pig *** rich on a nitrous tune. If I have any flawed logic or I am making unreasonable goals please let me know. I am still a relative newbie but I do
a LOT.
I look forward to a pretty lively conversation on this

Bret, is there something wrong with the factory valves? I was planning on going with factory intake port on the LS7's and just do some exhaust work so that I wouldn't need to go with such a huge split on my cam. Is my logic flawed here? What about the ET ls7's? I know that they are a little more, $3200 i believe, as long as I don't have to use the Jesel system, I believe I could swing them. I am open to almost any suggestions. Also really interested on seeing what the Warhawks do. Does any one else see valve shrouding as a problem with the LS7 heads?
