There should be traces of glue/loctite in the hole if that is the case. I doubt that this is the case, but people do strange things!
If the oxy/acet flame tip was played on the top end of the helicoil for about 5 seconds MAXIMUM the helicoil should glow red hot & stuff any loctite or epoxy plus anneal it enough to allow you to bend in the top thread for removal as pointed out earlier. You wont affect the alloy with that time frame--- be real careful where you wave that torch though, especially down an intake port, could still be some fuel in there--use small tip & dont put the inner (blue) kernal of the flame on the heli coil- thats the cool part of the flame.
BE REAL CAREFUL ABOUT THIS, I would hate your next post to be
