Bryan suggested I didn't put anything on the threads as it mucks with torque settings. Might have a bit of a hold up with my barrels now though.

Oil or WD 40 then as they look so dry - I would be worrying about any more rust forming.
DomP:
I think they appear dryer/rustier than they are in the photos but I'll wipe them down with WD40 for you Ted😉 I was thinking of putting some rust treatment on the shafts of the exposed studs to protect them once fitted.
Hopefully get this thing started before Christmas!

Looking good Don, that’s great progress and the cases look fab

Bryan is right about grease potentially mucking with torque settings. However, having threads like those with nothing done to them can also cause problems. The threads can getting damaged when the head and barrels are removed just by the rust/debris/crap that’s around the threads when you go to remove them. I always run a good die down the threads to make sure any rolled over threads are cleaned up, I’d also give them a thin smear of molybdenum grease before fitting the barrels, just to protect them from rust over the years they’ll be exposed. I also used to grease my threads and use a slightly lower torque setting to compensate for the grease. Around 2-3lbs lower. Around 14ftlbs iirc. Modern Hondas started to spec pressures with the threads oiled. TBH I think a lot of them got oil on the threads and especially the nuts back in the day, common practice was to throw all nuts/bolts in a tub as you dismantled the engine, we knew where they came from, we didn’t need to have them in separate boxes for example, lots of other stuff also got thrown in the same tubs, stuff dripping with oil, so the head nuts would be soaked in the oil coming off those parts. Didn’t seem to cause any problems back then tbh.
