I'm starting to think pushrods might be my thing.

I'm not sure why it broke. I replaced them, made sure the valves were opening and closing as they should. It's running good. Performance is the same so I guess nothing else is wrong. I think the bent one is the result of firing the engine with the exhaust valve closed.

Should I replace this rocker arm?
