TR4 cam bearing installation

[John Middlesworth <jape@email.unc.edu>]

I'm ready to put the cam bearings into my TR4 block, but I'm a little
confused about the setscrews I see illustrated in the Moss catalogue.  The
shop removed the old bearings without returning any screws to me.
Questions:
1. Did all the 4-cyl blocks use screws to retain the bearings?
2. Will I be able to fit the bearings in myself or will a machine shop
need to do it?
