what headers with Gt40p's
Im picking up a set of gt40p's in two days, and I know I will need different headers due to the sparkplug angle of the gt40s. I wanna go with longtubes, what brand will work. I heard ford racing and mac, is this correct?

I did not know that the spark plug angle is diff on the gt 40's.. are they are pointing to the front of the car?? I know how to tell the diff in them is due to the vertical lines on the front right? but whats the diff. in gt40's and the gt40ps?

my buddy has mac shorties on his gtp heads. they were for his old e7's,but made them work on the p heads. longtubes are better but, you'll have to figure out o2 sensor placement,heat issues. ofcourse fitment issues as well.

you got an aod?or t5? i've melted shift cables before. not fun. hell, my o/f h pipe is just about touching my trans pan. I've heard stories of guys having to loosen the motor mounts,tilt the engine just so they can squeese them in. But im sure going thru the bottom would be the easiest route on a fox body.
