you must use the same lifters that are in the motor, to get them to pump up soak them overnight in a can of engine oil, then take a pushrod and press down on the seat in the lifter while submerged in oil, do this untill no movement is felt. then install in engine and measure your correct length, the rocker must stay as close to the center of the valve as possible, starting on one side of center at rest then centered at 1/2 lift and over center at full lift, adjust pushrod length accordingly, allow for about 1-1 1/2 turns down for preload on the lifter.
