Can we see a shot of your exhaust system?
Given the amount of corrosion showing on that exhaust port, I would suspect you are having water or moisture intrusion into the manifold from the exhaust. This is a frequent cause of sticking valves.
A well designed exhaust should have the dry part go as high as possible (mine is 12"), and then inject the water at least 4" below the high point, but more is better.
