Dove heads are well known for pulling heli-coils out. The aluminum is too soft on some heads. My guess is that it is a matter of time bfore you see it happen on the other side. Call George at Guessford, he has many years of experiane with Dove heads.

As far as thread depth goes, in aluminum it should be 1.5 times length to diameter.
