I've just had bad experiences in the past with lubricating bolts/nuts.
So have I, in an automotive application. I had this same discussion with
Woody a while back. I'm not so much an advocate of oiling/greasing the
threads (even though I recommend it), as I am the mounting surface the
bolt head or nut flange cinches up to. This was a tidbit I picked up from
a crafty old engine builder with a long record of building championship
winning engines. His stance was, the lube on the landings leveled the
playing field so to speak, allowing the fastner to tighten up to a true torque
each time and not a friction dependent torque that could vary with each
attempt. I know in industrial applications as well as automotive where
the fastner is actually stretched to yield a specific torque ( so it is a one
use only and you actually measure the torque from the bolt stretch), the
manufacturer will specify a wet or dry procedure when torquing.

I advocate prepping threads on all fastners because of the real chance
of galvanization. Every nut and bolt on my bike is prepped with some
thing: oil, loctite, ti-prep, etc. I would much rather have a "wet" torque
than a seized fastner. Since I started using this technique, I have not
had a fastner fail or seize.

Every mechanic has their own techniques, this is one of mine.

The Honda factory manuals call for oiled threads. Like Infernal, I have not always been a fan of oiled threads, preferring as many do to use new and dry each time. "New" is not always practical. I like the stretch method but many fasteners do not have that information available. It varies by length of bolt or stud of course, just like torque figures do.

But, danged if I am not still totally perplexed by the breaking of these studs!! I see plenty of studs which were overtorqued pull out of their sockets on the same model of engine, and have yet to see one break.

You're sure you're using the ft/lbs scale on the torque wrench? I've had brainfarts and almost used the newton/meters scale before.

Also, is it the same stud that keeps breaking? Or are studs in different locations breaking?

Yes lol its a ft lbs wrench. The last 2 that broke have been the same one, the one before was the one right behind these last two

Well my wrench has ft/lbs on one side and N/M on the other side. 20 N/M is only 29ft/lbs though.

If the location of the broken studs is consistent I'd be a little worried it's something more significant though. Maybe a bent stud could cause it. Do you have any way you can check to make sure the studs are all true?

I dont think theyre bent but im not sure how i can check them. I might try all new nuts too this time see if that changes anything. Theyre just regular metric nuts i beleive?
