I think heli-coils are great given the right application. The problem with heli-coils in spark plug applications is that you don't have full heat transfer and it's not un-heard of for the heli-coil to come out with the plug in aluminum heads. Many manufacturers, such as GM, Honda, and Ford, recommend the Time-Sert to repair spark plug threads.
Just my 2 cents, YMMV, To Each His Own, and it's not my dog that's pooping in your yard.

Heres a link for the Timesert sparkplug repair........www.timesert.com/html/howtosp.html
This is a lot different than a std. thread insert.
Keep in mind that when doing any repair with a thread insert such as a Helicoil ,you can mess it up by not drilling a straight hole or by drilling an oversize hole.

Another new thing learned.... I love it!
I am curious about removing plugs from a hot head though....why not? I am sure that this is obvious to many, but I could use some explanation.
Thanks!

Hot steel expands and holds heat longer than aluminum. Thus the plug is hot and expanded while the head is cooler and smaller.

I'm not arguing with you but as I stated if a person only buggrerd up the first two threads you can re tap and retain its strength. Now if all the threads are streached then yes re tapping wont cut it.
