to me it looked like everything had oil on it ( wasn't dry, just that the lifter was ither not pumping up, or it was stuck.

That valve looked bent because the intakes are at a different angle than the exhausts. Glad to hear it started running better on its own. I'd try some Rislone in the oil, and an oil change after a few runs.
