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.
