...I shouldn't put a little tackweld on the back of the stud where it threads into the header? I just scored a screamin' deal ($75) on a like new set of FMS stainless shorty headers. My only complaint about these headers (my third set) is that the stud always comes out when you separate the pipe from the header, due to the self-locking nut. I thought a small tack would remedy that problem and be reversible in the future if needed.
