Adjust valves

How in the name of Buddha did you get the lash set correctly ?
With a hydraulic cam I have done this and given them the 1/2 turn past quiet , but that was with stud mounted rockers.
Shaft mounted has to be an adventure.
Chevy stud mount is a bit easier but it's really the same. Unless you set them running, the procedure is the same. Solids have to be adjusted from time to time.
