curious about valve lash setting/check

By adjustment description and the picture, I do believe some of those are adjusted so tight that some of the valves are probably hanging open.


I agree. All the adjusters should be damn close to the same adjustment. You've got some that have the adjuster buried in the lock nut.

Do it again. Use a soft finger and as soon as the lash is gone, just not even enough to spin the pushrod...when the lash is gone...screw that adjuster down 3/4 of a turn and tighten the lock nut.

Done. But all the adjusters should be visually very close unless the base circle of the cam is off from lobe to lobe. But I haven't seen that since 1982.
