It all makes senses now. What amazes me though is learning that heavy duty diesels use a lifter designed decades ago for small block V8 gas motors, who knew? Also, he stated that as heat and RPM increase, the lifter bangs on the cam, but how does a shorter pushrod prevent that? It more sounds like the pushrod bottoms out in the lifter, resulting in zero lash, causing the valve train to bind up, and the shorter pushrod allows a little more clearance.
