68-72 350 Exhaust Manifold Interchangeability (RH)
Are the (RH) Cutlass 350 exhaust manifolds the same/ similar/interchangeable for 68-70 and 71, 72? ( I assume they are, less slight casting number location differences...) ...thanks

1964 thru 1976 or so all used the #3 or #4 RH manifold. 2-bolt exit is down and aft at about 45 degree angle. Interchangeable.
After that came the #5? and similar tiny castings for 307's or 260's, all these sport a 3-bolt exit flange pointing straight down.

Once again, Olds never made a dedicated dual exhaust manifold for the small blocks in a RWD application. All factory SBO dual exhaust cars (including W-31s) simply had a cap on the passenger side crossover hole.
