When moving the studs from the downstream connection on the old header to the new header, I noticed that the side of the studs that goes into the header flange is not long enough to screw a nut on it. The stud is threaded into the header flange and then the spring is compressed on the midpipe flange, and that’s the only nut holding that connection in place. Is that correct? Or do I need to buy new studs so I can put a nut on the header side too?
