Looks like an AIR (smog) pipe to add fresh air to exhaust manifold to help gases further combust after they leave the head. The bowl-shaped thing is a check valve that only allows air to go in one direction (to exhaust manifold).... don't know how this was implemented in the 80s so that is the extent of my knowledge
Looks like the hose is just cut off? No air pump on the vehicle?

On my later 351 (94) the air pump is on the front bottom right, below the alternator and tensioner pulley. Looks like someone may have removed yours. You can remove this pipe and plug the holes with the right size bolts, if the condition of the manifold allows. Might not do so well on an emissions test though.
