Well now what?

If you’re using 273 style rockers, have they been modified to use lock nuts, or are the adjuster screws still just friction lock?

If they’re friction lock, do they all still have a good amount of resistance to turning?

They have not been modified at all. As far as friction still being present I would say no. Some of them I can turn some by hand. When I put a socket on a few of them to do my 3/4 turn preload there was very little resistance at all. I have probably not helped by backing them out and adjusting as much as I have either.
