Wait wait.... This made the refrigerator bulb in my head come on. If you look at the pushrod cup on a 1.5 vs 1.65 HS rocker, the pushrod cup moves toward the rocker stud on the 1.65. So the rocker ratio does change on the pushrod side. If it changed on the valve side, the rocker tip could run off the top of the valve when the ratio changed. Wouldn't that mean that 1/2 turn on the polylock would result in different lifter preload depending on rocker ratio?
