Default Advice wanted after Formato tune

Jeremy Formato tuned my '04 ls1 gto 2 days ago.
Final results were 383rwhp and 372tq.

I'm done modding it for the winter.
Only mods done so far are:
-Livernois Stage 2 243 heads
-TR 224/224 112 cam
-Kook's 1 3/4 LTs with catted mids
-K & N cai

catback and everything else is stock. car put down 282 from the factory, so I got a 100 hp gain.

Looking forward to next spring, and possibly modding more.........the question is...............
is 430-440 rwhp a realistic goal?
What would I have to do to achieve it?
I picked the TR224 cam because the car is my dd, and I wanted good streetability. It IS very streetable, but I'd be willing to swap the cam again if necessary. I'd prefer to not go above 230 duration, though, and retain as much streetability as possible.
Thanks.

If you want that kind of of power you will need to go bigger cam. Are you an auto or 6M? You might also go with some more compression like 11.5-12.0 for those power levels. 100 hp gain is alot of power to gain, that looks like some real good results to me.

Get rid of the stock cat-back add a ported TB and underdrive pulley.That should be around 410rwhp.I agree with raising the compression to 11-1,then add a FAST 90mm.That should hit your goal with the same cam.
