ive been following FTI's website on adjusting the valves, but the rockers still have enough lateral play that I can move them back and forth with my fingers. did I not tighten them enough ? my process has been tighten the nut down until i feel a little bit of resistance in turning.. enough to still easily turn the pushrod - but enough so i can feel that the rocker is at Zero lash. is this normal that they move back and forth.. or should I tighten down the rocker more so it becomes harder to turn the pushrod. any help would be awesome - as I am trying to drop the motor in ASAP.
