How about exhaust mods? Vortech spec MSDS headers might be nice, or optimize your factory manifolds. I'm sure the vortech is going to make it much more difficult to touch that front header since the jackshaft runs near it and it is already a pain-in-the-ass.
Pull your upper and lower intake manifolds and clean and port match them so you can get more air throught the engine.
Put on a larger TB so you can move more air as well.

Just some ideas that will help out no matter what you do.
