Thanks guys. Not sure I want to go with bigger heads or a crazzier cam considering that I just shelled out for both the cam and heads I have now about a week ago. I wanted the car to be a daily driver that would pass emissions. I do have hi-flos with the 3" exhaust, but I have an exhaust cut out system that lets me go open header at the touch of a switch. The three things I was pondering were the Fast LX with a bigger throttle body and a bigger Mass Air Unit, but I just don't know if those things ($1500) are going to produce vs. the cost. From what I've read, the fuel system and drivetrain don't like much more than 400 rwhp if you're going to drag the car, so I've ruled out a power adder for now. If I were to go with the manifold, I'd probably go with all 3 intake upgrades, but I'm just not sold on the validity of the gains. I've heard that gains can be very dissapointing, but I'm sure the right setup would benifit, just not sure if my setup would and it's a sizeable chunk of change after the mods I just shelled out for.
