I used JB Weld to do the one's in the Ranger. I would definitely rough them up or cut some grooves with something so the epoxy has more mechanical "bite". I had 2 come loose and had to re-epoxy them and they were fine afterwards. I did not rough them up but should have.
Life is short. Be a do'er and not a shoulda done'er.

Pipe threads, hmmm, I have some pretty large pipe taps, I wonder if I can get suitably large dies? That would be TOO easy.Escaped on a technicality.

What's the OD on the bungs. I have a set of H-F NPT taps and dies that should be workable just eyeballing the size of the injectors and your bungs that you had. The tap part would be easy, the die on the bung would be hard I'd think with the stepped shoulder potentially running into the die before you cut any sort of decent threads on it. I guess if you were epoxying them in that wouldn't matter as it would just serve as a way to keep it in place while the epoxy cured.
Interesting thoughts I'll have to keep in mind if I do a Nailhead or the call of those 1926 Buick I6's gets too strong and I drag them home.Central TEXAS Sleeper

The od of the bungs are 7/8" the ID is .550 . Taping is out of the picture.
I have a smooth finish on the bungs I guess I will have to rough them up. James did you use the high temp 400 degree JB weld or the standard 300 degree you see in the stores?

Finally got to dig out my good calipers and the tap set.
1/2in NPT tap has a maximum external diameter of 0.855in but the range I've actually used on it is closer to 0.820in.
1/2in NPT die has a maximum internal diameter of 0.765in and a minimum ID of 0.735in.
Sounds like they might work but good luck getting the die started on the bung and keeping it straight by hand.Central TEXAS Sleeper
