What are they original from? They have adjusting screws with Jam nuts.

I believe only early 273 engines had factory adjustable rockers

Look like stock 273 rockers that someone upgraded with locking adjusters good setup if they spot-faced the rockers for the lock nuts

I have early adjustables on my car for nearly 50 years now and they also have lock nuts on them. Never realized they weren't standard. I wonder if it was a change at some point?

I've never seen any "factory" 273 rockers arms with jam nuts and my first 273 was acquired in 1966. Some one faced the top of the arms and added the jam nuts, Ed Hamburger used to sell them on exchange system I believe.

I have 13 273's at this moment from 1964 thru 1967 and have no lock nuts on any of them. I can't even begin to know how many we adjusted at the all mopar only shop in the late 70's early 80's and I have never seen original an one with lock nuts...but I certainly have not seen them all. It's a great idea though provided as above resurfaced flat for best results.
