what you can do is take one of the old head bolts. then take a angle grinder with a thin disc and cut 2 or even 3 lines in the threads, from bottom to top. then run that bolt in and out of all the blocks threaded holes.

did this on my 3800. worked like a charm. theres vids on yt, search diy thread cleaner.

You can also rent taps at some parts stores if needed. Make sure to not run them in and out without some lube.

AutoZone had the thread checker. Looks like a m10x1.75

I was able to get threads cleaned out. I got blocked cleaned. I set the main bearings in the crank underside and top caps on. Will check clearances this week on crank bearings. Then ring gaps and connecting rod bearings. It feels to be making progress. I am not rushing and taking my time to get it back together.

If you have the time it is best to "measure twice and cut once".
