Intake manifold, 350 GM

Good LORD that looks way worse than any part of my raw water cooled motor used in salt! don't know if that could be saved with rust converter, might be worth removing all the loose rust, then poke at it with a pick see if there is still solid cast iron there.
Normally a rotor just pulls off but I see 2 hex headed screws there maybe those have to be removed?
Merc guys what say you?

While this may or may not be a GM Distributor, Rotors on GM Distributors, were almost always secured with screws, as they sat on top of the Advance Mechanism
