Stripped plug threads
Anybody had any experience with stripped plug threads in a 460 Big Block?
Heli-coil the recommended fix or is there another preferred option?

Heli will be just fine, and is preferred way of many mechanics. Be real careful when starting the tap so as to be true and square.

I think Helicoil makes a spark plug thread repair kit. It will probably be a 14mm thread. The cleanest and safest way to restore the threads is to remove the head from the engine, but you can do the repair with it still installed, just coat the tap with grease to catch all the metal chips.
