I'm still unsure what to do about the three stud holes that had gotten 1/2-13 bolts forced in by some backyard mechanic who shouldn't have been working on cars. Fortunately they weren't in far so the 7/16-20 studs seem to thread in but are not as tight as they should be until threaded in farther.

The only thread inserts I've found require drilling out the holes to 5/8" so wondering if I need to go that route or if threading them in as they are with some good sealer might do the trick. I'm not sure I even have a way to drill a 5/8" diameter hole into the block! It would be better to pull out the engine and have it cleaned inside and out with the threads properly fixed but I don't want to go that route either.
