Or if you will tighten the head nut before the Loctite cures, use it with care. But if the Loctite cures before you tighten the head nut, you are in the danger zone of having issues. Often the Loctite gives way and you feel and hear a snap as the Loctite gives way when you are tightening the head nut. The torque wrench clicks, or the angle gets all messed up and you have no idea where you are. My advice is, do not Loctite the studs. Use some grease and back the studs out at least turn. EPG sold by McMaster-Carr is a good grease.
Interesting, Some of the head stufs threads come with what looks like some sort of Loctite on the thread ends which go into the case, would you clean this off or leave it?
