With the rocker torqued down, use the adjustable pushrod and adjust it until you properly find zero lash. Start from 6.80" and every turn is .050". Do this for several intake and exhaust valves and take the average length. Take that length and add the proper preload for your specific lifter. That will give you the pushrod length you need.
