Default LQ-9 370ci with LS-3 Heads and Intake Swap

I just ordered some LS3 heads and intake. I have an LQ-9, forged internals, running 60lb injectors, thru a T-56 and 3.42 gears, with a T-76 f/m turbo and 317 heads and an LS-6 intake (no port work to the 317's or the ls-6 intake). Last run, the car did around 530 rwhp on mustang dyno. What am I to expect with the LS3 setup on my car?

In addition, in order to do this swap, what parts will I need (worst case scenario) and could I use any of my current parts with the new heads and intake?

you'll need a Throttle cable bracket, ls3/l92 specific rockers, and if you dont have aftermarket rails, you'll need those too. Or find a set of l76, ls2, or ls3 rails. Also a 90mm TB (4 bolt)

Is this swap worth that much hp? I may build a 370 with ls6 and 317 for budget, but if it's worth the extra hp I may do the same.
