Have your guy be super careful with that torch, aluminum doesn't give any warning before it turns into a liquid. Its melting point is roughly 1200 degrees which is a lot lower than the 2000 degrees propane burns at, and mapp or acetylene burns hotter especially if mixed with oxygen. You should only need to get it up to the point where solder will melt on the stud (400 degrees), if you have some silver solder (which melts at 800 degrees) you can use it to test how hot your getting the stud. Like Kurt said by the time it is glowing red your already past 1200 degrees on the stud and probably dangerously close to melting it right out of the head. Also work the stud in both directions when trying to remove it, that one goes for any bolt/nut/screw that id difficult to remove.
