Funny...... “a good chance of being correct”.
Uuhhh.....just look at the wear pattern on that used cam.
The wear pattern shows you how the taper is staggered.
Just for grins, I just took a new SBM Comp custom and checked it for taper.
Right at .002....... with the taper staggered just like the used one in the pic.
That’s how they’re supposed to be...... and that’s how they are from the factory.
