curious about valve lash setting/check

oldlover; Assuming the lifters are new and empty of oil, it is difficult to adjust hydraulic lifters using the pushrod turning method. ...
To adjust: back off each hex adjuster until you feel clearance [lash] in the rocker arm. Then tighten the hex until there is no lash. Then tighten hex 3/4 turn and torque the lock nut to spec. By the 16th time you will be good at it. The 3/4 turn is a guess, others may know more.

That's the only way you can adjust new or empty lifters. Were only tightening the rocker until you can feel the pushrod/lifter hit the adjuster, ie drag. You can bleed out any modern lifter cranking an adjuster down to 'stop the pushrod from spinning'. If you adjust to touch then add 1/2, you have to be good (unless your lifter requires more ie Rhodes). You got a dry lifter: you can push the pushrod into that thing 1/4 inch and just compress the piston spring. Let's see what works best for the OP.
