Head/Cam combo for 383

I am putting together a forged Eagle bottom end 383 and want to know what Head/Cam combo works good to put about 450hp to the rear wheels. Any suggestions? The car is built (or being built) as a Xcross type car. I don't see myself doing any 1/4 mile launching. I have searched the threads and see mixed emotions with the flow #s. I am porting out my intake to accept the 58mm T/B. Any help would be great before I start tightening up the bolts......
Thanks.

Forgot to ask about the fuel delivery. What size injectors would be safe to run with the setup? I see everything from 30lb to 42lb. Thanks again for the help. Hopefully I'll be posting some dyno numbers before Christmas to help out someone like me

AI or LE, your choice. Personally I'd go AI. I'd say at least 36# injectors, but get #42 just to be safe.

Flow numbers aren't everything. Call them first and tell them what you want and what you're using it for. They'll have a custom H/C setup for you that will maximize your setup.

I would second AI, though I think your goal is a tad high for an AutoX motor, I know thay have done exactly that with results near that already though.
