383 stock rocker shaft assembly question

Firstly, I hope you've all had a nice Christmas :thumbsup:

My question to you, should the pressed out stock steel rockers be a nice snug fit to the shaft, maybe a few thou clearance or so ?
I know all the aftermarket stuff is either bushed or needle bearing, so I guess the stock set up is similar in intention to have a smooth rocking motion but no real play ?

I've looked though the manual I have but not seeing any spec for ware or serviceable clearance ? have I over looked it ?
I'll wait...
