With aluminum heat can be a real problem, it melts at such a low temp. you 
have to be careful.

I've resorted to drilling out the old bolt, then using thread inserts to 
restore the threads.
Broke a spark plug off in a cylinder head on a 3800 v6 a few years ago, 
that was the only
way to repair it.
