As he explained it to me and I'm not technical either
is this. The helicoil is a spring. The cylinder is bored out ( this should be done with the head off in case any bits fall in) with the new thread that is now larger than the spark plug. The coil is now threaded into the hole and the plug placed in. I think maybe he was thinking of expansion/contraction and working loose.
He mentioned another method but I can remember the name. I think in effect you bore the hole out and put a new thread in. This in some way is a more permanent method.
Now that really was not a technical explanation. When I next talk to him I will get the better answer.
