440 valve rocker arm shaft questions

The Mancini rockers are Harland Sharp bodies without the roller bearings, I've heard nothing but good things about them. They seem the best value for dollar, and you don't need a lot for a flat tappet, but the stock rockers aren't adequate. If you can find the Erson/Crane/Mopar ductile iron rockers, those are perfectly adequate as well. S/F.... Thank you Mancini is onacry an hour away from me

I may take a ride down to Mancini racing this week since they are only an hour away.

Thank you
