Okay, I def will Only problem is it would be running bad/idling rough if the valve was bent.

Not really i had 2 bent ex valves and still dynoed at 420 rwhp and the car idled smoothly. Probably a slight bend like what i had 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?

Pretty sure crankcase man, I think I can hear it in the dipstick tube and on the other side of the engine coming out of the push rods.

What is the result of the compression test?

To leak air out as fast it's going in, you got something other than ring problems.

I would think that you would be getting P0300 mis-fire codes.

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.
