What happened to this push-rod...?

[Tommy Molotov]

The end is all chewed up. I put a new one in, but even the new one sits too low for the valve adjustment screw to properly reach. Before I start tearing things apart, what should I expect?

the cam or the follower are disintegrating? I wouldn't ride it..  have you got the Roper plate? oil starvation comes to mind..

[Tommy Molotov]

Could be I guess. I don't have the Roper plate. Oil's always been kept at the right levels, so I don't know what to make of it.

Cams and tappets are fed by splash, plate won't help there. If the adjuster won't take up the slack though the only real option unless the pushrod has collapsed is a buggered cam and tappet.

The cam and lifter have failed and the greatly increased valve clearance thus created has hammered the pushrods into what you now have.
