does anyone know if different screws are needed for the installation of nismo headers?

 

anyone? my mechanic was going to install them but he explained something that i did not understand which is the reason why he told me i needed different screws

 

First off they are studs. And the problem is to be able to get the headers on, you have to swap the position of the middle two studs. If he can't figure that out....then he's not a good mechanic.

 

thanks for the advice. Sorry, english is not my primary language, the reason apparently was because they are too long and i have to remove them and find some screws that are shorter, im not sure if it is because of the thermo wrap, i have to talk to him to be sure of whats going on. If not ill just wait until my uncle arrives from LA since he is a z specialist technician (300zx)
