There's only three header options for the 370Z that are worth the effort (proven power increase). FI LTH's, PPE LTH's, Z1 shorties with their TP's.
OP, if you're not willing to sell your current TP's in favor of one of these options then IMO don't bother with the headers. As previously mentioned, the install is a PITA so if you're not gonna gain anything then don't put yourself through the hassle.
