67 LA Exhaust Manifold?
 

Does someone here know what exhaust manifolds would be correct for a June built in LA 67 L78? A friend of mine is putting his car together back to stock and is not sure what it should have, as there are a few different BB manifold choices.

should be part code RH 3809880 and LH 3809879. These are for A.I.R equipped cars manufactured in LA

Thank you!

Only if the car was originally delivered in CA. Otherwise it would not have smog equipment.
