headerz

I believe the only headers that will work with GT40P's are the specific one's made by Mac or FRPP.

Anything else like your LT's would get in the way of the relocated spark plug angle. Good luck.
 
SOME e7 and regular GT40 style headers WILL work with the P's. You just have to modify the plug wires ... or get a different style all together.


Now as far as which one's .... I don't know. So BBK LT's may or may not. :shrug:
 
From experience stock defiantly don't work, and heddman long tubes do not work. Ive heard the bbk's work with a special socket for the spark plug but i don't have an experience. I went with the frpp p headers just for ease of install and not have to worry if it fits. Long tubes are a pain in the ass and just not worth it.

And headers is spelled with an s.
