I have a 360. Has headers on it now, but they're kinda trashed and I don't know how to identify them. Would there possibly be a stamping of a part # of some sort? I've found a few that say they fit my vehicle, but the footnotes say not with a 727 trans and only with a mini starter. Obviously, there's some company out there, because I have a set on my car now. Any help would be appreciated.
