I can’t help with head removal but do wonder how the exhaust valve got bent.
Running without one exhaust valve opening shouldn’t hurt anything as some engine designs have done this intentionally for various reasons.

Probably stuck open as a result of being bent so it will not run right with just one valve.

Without the finger follower, the camshaft probably came around and hit it sideways. I can see that bending the stem.
