Slowly heat the nut itself and the head. Touch a plain old stick candle to the thread area and also the exhaust tube area. The wax will wick itself in and HOPEFULLY let the nut come out without damaging the threads in the head. Let it cool a while and try to turn the nut. If you have a proper nut wrench, giving the handle a sharp rap with a hammer ONCE should break things loose. Good luck!
