If you still using your factory computer and valvetrain, I would probably consider upgrading those first along with some sort of fuel tuning device (like a V-AFC). You have a good set of cams, but your really not taking advantage of everything they can offer without upgrading the valvetrain and tuning your fuel curve to take full advantage of them. That's probably what I would recommend. You'll probably see more power gain and a smoother running engine with some tuning and a better valvetrain than you would with any real engine upgrade looking for power. Seeya.
