I have a Hawk and also faced the problem of a broken off exhaust stud. I took the engine out of the frame and tried to remove the remaining stud and that one also wrung off. Rather than extract the broken pieces still in the cylinder head I drilled and tapped new holes beside the old stud locations. There is enough room for them. A machine shop I consulted recommended I drill the new holes to a depth 1.5 times the diameter of the replacement studs. I did and the new studs are still holding fine after several months. So, you may be able to use your head (the one you've already got) to hold your Magician together.
