You did this as well correct?

"rotate the engine in the normal direction of rotation until the exhaust valve begins to open. At this point,
adjust the intake valve to ZERO LASH with no pre-load at the lifter, then tighten 1/2 more turn. Rotate the engine again until
the intake valve has fully opened. Now you can adjust the exhaust valve to ZERO LASH, then 1/2 more turn. Repeat this
procedure until each cylinder is completed."
