I have already added 4.10 gears and a 75 mm Accufab throttle body and plenum. Headers seem to be the next logical step. Due to ease of installation, I was leaning toward JBA shorty headers. But, most posts on stangnet seem to favor longtube headers for performance. Since the cost for JBA shorties is comparable to longtubes, I will probably go in that direction. For my automatic, however, I am limited in my options. The best option seems to be Hooker headers. Does anyone have any experience installing these, or can you recommend a good website?
