Quest for 400hp

My new goal is 400hp

Right now i have
GT 40 aluminum heads ported
Typhoon intake ported
331 stroker kit with keith black flat top pistons
cold air intake
Comp Cam with 282 duration
24lbs injectors
70mm throttle body
70 or 75mm mass air
bbk equal length headers

I imagine i will need some better heads, intake and bigger injectors.

Any Help
