I've never seen that before but ii've seen a cat get that hot from being pluged
burned valves or very thin tubing

Yeah, I would go with thin tubing... What headers do you have?

Uh...that is still sounding weird to me...what were your engine temps at the time? Did the dyno shop have a large shop fan blowing air into your radiator while you were testing it?
Having red hot headers is ok, i guess, but just don't let the plug wires--or any other wires for that matter--touch the headers...

You told me a/f ratio was 12.2 : 1, which is plenty safe. Now if the sensor the shop was using is old or inaccurate, it could be a lean condition.
