Best heads for a boosted 6.0L

[jetmech]

Like the title says, what would be a good set of heads for a boosted 6.0L? To be more specific:

-I can commit around $1500 to a set of heads
-I prefer thicker decks
-I'll be throwing about 15 psi through this engine
-I'd like a set of heads that flow like, or better than, 317's

I've entertained the thought of obtaining a used set of 317's and just sending them to west coast cylinder heads or one of those companies that specialize in heads, but I'd also like to know where I can buy a good overall set of assembled and ported heads that will work well with what I am trying to do. This build won't be anything crazy. I'm only looking to make up to 800 at the crank, maybe the tires. I've been away from the performance domain for a few years now, so I realize I may be asking a question that has been answered about 27 times already. Suggestions?

Ever thought about an L92 top end?

to make 800 FWHP any head of the LS motors will work...if you want to spend the coin then look for a set of used ported 317s or etc all depends on compression goal

I have a set of these:
GM PERFORMANCE AS CAST RECTANGLE 260cc LS3 HEADS WITH PAC DUAL SPRINGS, SEVERE DUTY INTAKE & INCONEL EXHAUST VALVES.
brand new but slightly used as they been down the track 6 times.....pm me or farmtruc if interested

I say send some 317s off to WCCH they might as well be the gods of heads and should fit your budget. 243s are another good option if you want more compression. 317s and 243s are dang near the same with different combustion chambers. I would stay away from factory casting rectangle heads if you are concerned about deck thickness. If it were me I save money for other things and get some mild worked 317s.

If you are interested I have a set of mildly ported 317's with larger valves.
