hydraulic lifters

Are you sure that "spinning" the pushrod is a good way to check if it is properly adjusted?

Hydraulic lifters bleed down if there is pressure put on them for a period of time, like having a valve open for example. there will always be an open valve or two on a v-8 at any given time.

What are the proper rocker arm adjustment procedures recommended by the manufacturer of the lifters/rockers?
