yeah, i have gt40p's. i had to put different headers on. had equal length short tube headers but had to which to mac short tubes because of how the park plugs are angled. the tubes were in the way of the sparks plugs so i couldn't tighten them. had to go with Mac short tube headers. i aint mad though because my set up sounds incredible, no joke.

the gt40p heads require new headers to clear the revised spark plug angles, talk to bbk they will set you up with good headers.

gtp heads need gtp headers i think gt40s dont go to fletchs 5.o and look at head flow#s

my bbk shortys worked you will just have to remove the driver side header to get to one of the plugs.

i now have MAC longtubes, they work great.

btw i also used a 90 degree gm sparkplug wire, because on that same plug that had the clearence issue i burnt up my boot very bad and it started to arch off my header. with a 90 degree it clears big time.
