mismatched exhaust manifolds?
I just noticed that the exhaust manifolds on my Cutlass have different ID codes. The driver's side has a big "1" at one end and a series of about seven numbers in the centre. The passenger side has a big "4" at one end and that's it. Should these exhaust manifolds be on the same engine? I'm guessing the car originally had single exhaust (it now has dual 2.25" exhaust).

The number 1 and 4 manifolds were used together for several years on 350 engines so I think your OK with that. It's good that it was changed over to dual exhaust though, that will help it breath better than the crossover pipe and a single out the back.
