Right on.. just trying to find a cheaper way to get a reliable solution.
Did a giant glob of aluminum come off with the plug?
If so, I can see the case for a new head or removing the stock one to repair it. But if it's just enough to fill the threads on the plug, I'd bet you can install the helicoil without the hassle of yanking the head.
