440 Rocker Shaft is it usable?

my first concern - have you tried to get the rocker arms onto the shafts? I would think they would go but... if they do, these should take to a polishing and be good to go.
How many foot pounds would someone have to have used to do that to them if it's not original?
Just food for thought - new ones aren't too expensive.. piece of mind is priceless.
