Im doing a 4 valve swap in my 01 GT, I compared my header gasket the the 4 valve heads and they look similar. My question is will 2 valve long tube headers work on my 4 valve heads or do they have different ports or is the 4 valve engine alot wider that the 2 valve? Anybody have any experience with this?
Just wondering havnt had the manifolds off and they looked so similar on the outside. If I buy long tubes for the 4 valve will they match up to my catback? Or will i have to change out my whole exhaust system?
I have a 4v teksid in my garage with 50k miles on it, Im lookin at getting the C heads and an 01 intake manifold and someday a 302 stroker kit and single turbo kit . But im stuck with N/A till pry next winter
