Copy paste and keep....
Live it, learn it, love it!!
I ad .002 when cold.
273 rockers are great, BUT the adjusters are a bind fit. Good the first few times, BUT wear easily and stop holding there adjustment after time. You can buy after-market adjusters from comp through Summit. they'll have a lock nut on them to hold them in place and they are hardened. You have to fill the top of the cast like so...

So the new set nut will tighten flat.
If they don't stay tight problems will follow...
My-2...

Never had a problem with 273 rockers. The most I have on a set is 400,000. I've adjusted them 2 or three times, including startup. They are either tight or not. If loose then your fix is good. My max lift is .500. I have no experience with more than that.
