The only way to hit 400rwhp with ported heads is by adding an intake manifold that will raise the point where peak power occurs, like a 5-6" short runner, sullivan or FR500. Naz's ported head, 10" short runner, cammed (similar to 106400s) combos made 380. The bottleneck is the intake.
Dynojet?

I was on a dyno dynamics. Chances50 has a setup that made 535 on gear headz dyno then made 498 on the dynamics... My car probably put down 400 before the catastrophe, I am confident that it will do so with the new setup regardless of runner length or intake.
