Changing your own cam bearings?

Yup, good info. Years ago I had a buddy who owns a shop change one flaked bearing in an otherwise clean short block, cam removed. I brought him the short block on an engine dolly, the bearing (I had to buy all five in a set), he knocked the new bearing in, in the bed of my pickup, $50 labor, ouch.
Yikes! He charged you $50 to do one bearing?
This is why I'm going to find a way to do it myself. And I may do what you did and just change out the bad one.
