Only problem is it would be running bad/idling rough if the valve was bent.

Not a huge bend just enough to let out pressure. its a possibility right and easier than checking the rings. When you hook up the compression tester wheres the air going the crank case? or out the intake or the ex?

The rings should have been seated by 500 miles.
It doesn't seem to me than an over rev would cause multiple cylinders to suffer ring failures without anything else happening. Usually you get away with it or you damage other parts like a piston, a rod or valvetrain parts.
That was my thought too.
