The cylinder bores for the cam followers do not have any holes or passages so it does not matter which way as far as the cylinder goes. However, the followers should be put back in the same way they came out if they are used because the face has mated to the cam.

Blue the cam and followers and check the mating each way.

By looking carefully at the cams and followers---including using a magnifying glass--you might well be able to match follower to cam.
Worth a try!
You really want the matching follower and cam combination to be retained---as they have worn together over miles and time.
Mismatching means they have to start over in terms of wearing together---at best that means adjusting tappets more often and at worst could mean very rapid cam or follower wear and a noisy motor.

I've always been able to put the cam followers back in their same positions, but I wonder what one would look for in terms of wear. It seems to me that in order for the wear to be uneven, the cam follower would have to be not square with the cam lobe. In that case, I guess the scuff mark would be wider at one end than the other, and likewise on the cam lobe, is that right? Or perhaps there would be tiny scratches caused by irregularities in the surfaces? That would be like ballistics analysis.

If the wear marks are uniform throughout, then I guess the followers could go back in any position.

A combination of all of the above.
It is a bit like detective work.
Remember you only have to identify three matching sets--the fourth is easy!

I will definitely give it a thorough look to see if I can match them up.
