Long story short, my buddy stripped two of the four spark plug threads while I was running a compression test, trying to help me finish up so we could get on the water. I was able to fix one of the cylinders with a helicoil, but the other cylinder was somehow too loose for a helicoil. It would require a Big-Sert Time-Sert, which I can't get for another two weeks since I live in Canada, and they cost the same as a used head that I can buy locally from a parts outboard. I already pulled off my original head and gave it to a local machine shop that quoted me $200 CAD to get it done, but that would also take two weeks. I was curious to know if the head from a 1976 85hp would fit so I can enjoy what's left of the warm days on the water
