Rotating the push rod is affected by the lubricant; sometimes the lubricant on your fingers! Both ways work, you should use the method that works best for you.

The Intake Closes-Set the Exhaust and Exhaust Opens- Set the Intake method gets the lifter on the heel of the cam lobe. It is certainly a good way to adjust.

FYI, for a 3/8-24 stud thread, each 1/2 turn of the rocker arm nut moves the rocker arm down appx 0.021" times the arm ratio = about 0.035" for a 1.5 arm.... if my head is working right today.
