I keep the intake off until I've rotated it(by hand) to hit the 2 "sweet spots" where the top is being oiled then I take off the rocker shaft assy's & add some more goop to the lobes & reinstall rocker shafts/intake & button it back up. R&R ing the rocker shafts doesn't change the lash settings. A bit excessive but I'm getting that way in my old age.
