Ok, I've been thinking about this and I think I have it figured out. At first glance, I would think that the push rod is too short. But thinking it through, I think it has to do with which side of center the contact point (rocker to valve stem) is on. If the contact point is less than 90 degrees (3 0'clock if the rocker stud is pointing at 12), a shorter rod will bring the wear pattern closer to center on the valve stem. If the contact point were greater than 90 degrees, a shorter rod would push the wear pattern out closer to the exhaust manifold.

Is my thinking correct or am I over complicating it? Sorry for the hijack, but this post got me thinking about it.
