Stock OE would be a high flow drivers side with 2 1/2 outlet and a flange on the manifold for a heat stove. On the passenger side, it's a log type manifold with 340-360 ports and 1 7/8" I believe outlet.
For reference these have 1973 model year date codes. But the part numbers are the same: [SOLD] - Pair of 73 340 exhaust manifolds
For reference these have 1972 date codes: [SOLD] - 72-73 340 Exhaust Manifolds
