Keeping boost at 5-6 psi and tuned properly, the Pro-charged setup will do fine with that compression ratio. That's basically the set up that Pro-Charger sells as kits for factory LT1 and LS vehicles. Now is your cam compatible with boost? That would be something to investigate.
Deadnuts reliable and cheap but make good power? Get a Gen3 6.0. Stroke it to 402 cubic inches with a 4 inch crank. Put stock or ported L92/LS3 heads on it with a cam that will produce broad power but not be radical. You should be upper 400s to 500 at the wheels with a great and very fun to drive torque band. Hell, save money and stay with Gen 3 heads. It's not like ported LS6 heads are crappy or don't make power. I'm fairly certain this is the route I'll take.
