mopar shaft rockers are in the ballpark geometry wise most of the time with made in usa rockers.

I humbly Disagree,
---contextually---
Let Me reference main bearings, go buy 4 sets of bearings , I bet You find
at least .002-.004 variance in production tolerances.

We would buy 10 sets of bearings, Yes 10 (ten) & 'match' all to the build design...

Rocker arms ??? all bets were off, Rocker Shafts, never seen more than .005
variance front to rear measured at 4 points along the vertical & horizontal centerline ...

Edit, ^^^ 48 small block builds... We had a milk crate full of 273 adjustable rockers,
took about 2 hrs per build to match the Rocker bore to the standard 7/8---.875 ---shaft.
Can You say side loading??

I now relinquish the floor Mr Beachel, :D
