Camshaft ID issue

Hello all, I am currently rebuilding the 4.2 engine from the stalled project that I bought. I have found errors made by the PO, e.g. intake valves in the exhaust bank, so I am looking for help in identifying the intake camshaft from the exhaust. They bear the numbers MC 20889. 8 and MC 20889 2.
The car is a '71 2+2
Thanks
Mike

With the cams set at TDC the front lobes point outwards.

Look here.

Thanks, that’s clear enough.

NOW Ive heard it all…:disappointed:
