Been away from the 'gearhead' stuff awhile and the memory cells are a bit depleted.

I'm re-assembling the upper-end of a SB Chevy that's w/ a hydraulic cam.
What's the proper pre-load for the rocker / lifter nuts?
With each lifter on a cam lobe base, after the push rod was slightly snug - I went an additional half-turn w/ the rachet.
Am I remembering this correctly for the initial set before I can adjust it while running?
