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?

You're not going to get aftermarket heads for that price.
Pick up some 317 castings and have richard re-work them for you.

There was also a used set in the classified section recently that might save you some coin.

Ls3 L92 Heads, about sam CCs as 317s and outflow them big time without need to port them, thus more likely more bang for the buck.
