Valve lifter is easy
With the engine at running temperature slip your finger on the valve lister and pull just enough to take all of the slack out of the cable
If you feel a tapping on the lever it is too tight so you go to the front engine bolt that anchors the cable & back it off 1 turn ( easier said than done ) then repeat the above test till when you take the slack off the cable you feel nothing on the lever
For some weird reason people think the vlave lifter has to raise the valve a large amount when in practice a couple of thou is all you need and I find that is better because you can hear the charge whooshing out of the cylinder better
