Most, if not all, low HP engines used the 2" exhaust. The higher HP engines went with the 2 1/5" exhaust, but all engines had the 2 1/5" manifold outlets.
If you plan on doing NCRS Judging, it's best to use the same type of fastening as original. Without looking at the AIM, I couldn't say which way yours was originally, but it's safe to say that the head/intermediate pipes were most likely clamped. Some years had mufflers welded to the rear pipes, some were clamped....same with the exhaust extensions/outlets....some welded, some clamped.
