Actually i had a helicoil comeout with the #3 plug on my old 73.. boy.. it can really make you hate them fast, especially after stuffing it back in and 3 days later blown back out again on a steep hill.. along with some of the surrounding head. I dont like the inserts eather.. I could never make them thread and fit properly, or even go in at all without using liquid Nitrogen... Ahhh,, the old days.
