Exhaust manifold identity

[Moparnocar]

Got these in a collection of 66 383 parts, 1 has the # 8830820 on it, any idea?

Part number for the one on the left?

Late 70s bb manifolds for a b or c body. Driverside will hit on steering column on 72 and earlier b body. Might fit on a 73 or 74 b body bb ..maybe??? Common to see in 75 and newer cars.
