We'll get it figured out.
With the repair, the threads on the elbow are new, and at first glance, one would think it an NOS elbow. My son is an outstanding welder.
Again, what would be a good sealer for the threads?

Any pipe dope is a good sealer but it will burn off @ exhaust temps.
you really don't need it.
a 1"
pipe tap hopefully will get the threads cleaned up in the outlet.
and go from there.
As far as what I was talking about in making the thread on the nipple larger, it needs to be done on a pipe machine with an adjustable die,
not a small hand operated non adjustable homeowner die.
Larger hwd and places like Home Cheapo and Blows have pipe threading services/machines that can adjust the dies open or closed, from the std size. it is just a matter of loosing a bolt on the die.
You might have to purchase a short length of pipe or 6" nipple long enough to be chucked into the thread machine, and give your son additional practice welding another nipple, make a trial fit in your newly chased thread in the block to assure you like the fit.
Usually 1-1/2-2 turns hand turns tighten then the pipe wrench finishing it.
I have used antisize to get tight enough to stay, but you don't want to put a cheater bar on the pipe wrench or you might split the head spiggot.
