If they are fitted for the application you shouldn't have any fitment issues. However, I haven't seen any for the 2v trucks, but banks does have 3v headers. If you are trying mustang headers, I'd like to know how it works out.
Thats what I thought, I would like to, but I am not about to shell out that much for new ones, I will have to see if I can find a good set of used ones with the h-pipe. I may just go with the shorties, but I wanted to go for more of an increase in torque.
