A heli-coil is a proper and effective repair.  It is done as a routine matter 
of manufacturing with quality aluminum engines and cases because it is far 
stronger then threaded aluminum, and it doesn't corrode.  Works well in iron as 
well.  The biggest problem with a helicoil is that they do sometimes back out 
with the threaded member.  Be it a bolt, a stud, or a spark plug.  Just 
re-insert the heli-coil, or install a new one, and continue.
