Matt,
Most of the time the cylinder head studs would come off without the need of heat using a collet and impact wrench. And a few stubborn ones like what you are experiencing now. Applying sufficient heat at the spigot area is the key to breaking the bond between the stud and the crankcase. Once the adhesive bond is melted, the resistance is reduced tremendously that you could easily remove the said stud. MAP gas will work but takes a lot longer heating time compared to an Oxy/acetylene torch. The crankcase is a good heat sink and could absorb a lot of head before you could melt the adhesive between the threaded section and the hole. You are doing well and keep up the good work.
