I measured for push rod length today. I set the cam so the lifter was on the base of the lobe. I backed the rocker arm adjusters all the way out and put the adjustable rod in and adjusted it till there was a slight drag when spinning it. The adjustable rod measures right at 8.5 inches. The rods I have are 8.425 inches. With either rod in place, there are no threads showing out of the rocker arm, even after I add an additional half a turn as if I were to set the preload. So, is there any reason I cannot use the push rods I have?
