Is the rocker stud broken?

You really need to pull the lower intake and look at the lifter and cam as well. I willing to bet they're both damaged. As giddyup suggested, I'd pull the head and look at the piston too.

Trick flow heads/rockers? Trick flow cam too?

Also, the polylock on that rocker is set in a different position relative to the rocker next to it. Do the other cylinders have a difference in polylock height btw exhaust and intake rockers?
