I have a 98 GT. I've never been to track, but my car will soon have these mods: PI Intake, Heads, and Cams, MAC LTs, BBK X-Pipe, Flowmaster American Thunder Cat Back, Shifter, and UD pulleys. Anyone have any idea what kind of horse power numbers i will be creating with this combo. One thing i am sure of is that i HAVE to get gears SOON. Would be a stretch for me to think that i will be close to the 12's with this combo if i add slicks and gears?

I had 261 RWHP w/ basically all the mods you have plus I had a dyno tune, AFM powerpipe, and Pro M air meter which do basically nothing on a n/a car. By your headswap you should now have more compression than a +99 (I'm sure you knew that but) so I'd say closer to 280 
I'd also say very low 13's w/ traction, and gears.
