Did debris drop into the cylinder? Any current compression specs?
That's what we were worrying the most about. Took it very slow, tried "cleaning" the area in the process. Some very little particles for sure got inside, but no issues that I could think of. I didn't do a compression check.
After following this thread, I must have got pretty lucky. I replaced my plugs earlier this year at a little over 50k miles and #5 wasn't even hand-tight.
