I'm pulling the engine for a refresh because it's got 80 hours on it. I did the leak down with the headers off. Even sprayed soapy water on the valves to watch. It's definitely both valves but only cylinder 2.

Overrev? Definitely. Several in fact so this is the most likely cause. When I wrote it it didn't occur to me that both valves would bend, but of course this makes sense.
