I doubt the low 11's with head work. A good set of cams and springs will net you about 40-60 hp with a proper tune. You are going to need gears (4.10's or 4.30's), ud pullies, CAI, drag radials (good ones like Mickey's), exhaust, some suspension work like rear shocks, control arms with a relocation kit for the lower arms, probably the head work, and a custom tune ON THE DYNO to get the most out of the tune. I'm pretty sure that's what it will take without going on the bottle. That should get you in the 11's if you can drive.
