This is good advice. As I understand it, proper cam - cam follower
design is such that the follower is not exactly aligned with the center
of the lobe, as well as being slightly convex thereby adding to the
rotational force affecting the follower. Besides, the engine is already
cracked open and followers are cheap. Sounds like insurance to me.
