I can fix stripped out threads myself,  I wished it was that simple. The guy hit a rock or something on landing and tore the valve cover off the engine, which in turn removed some of the head and all of the places where the valve cover once bolted to. Its really a shame to I just rebuilt the engine and it was running great for him.
Thanks for the info I may go ahead and get a head for the mag I can always send it back if its wrong. 

Let me ask this also does anyone have a used head they want to get rid of? if so PM me.
