Stock Hydraulic Lifter Preload Spec?

If I remember correctly, mine were 1 1/8 turns counter-clockwise from 0 lash.

1-1/8" turn on a 3/8-24 adjuster would only give you .047"; about half of what that cam card calls for. Also, I'm guessing that spec is for Hughes lifters. I need the range for factory replacement lifters. Thanks for the input though.
