Setting valve lash with new, non filled hydraulic roller lifters

Yeah, I knew they had internal springs, but I didn't know if their operating height was the same as their new, un-oiled height, but I'll give them a whirl. Thanks for the advice! What's your take on preload? 1 or 1.5 turns in after pushrod bite?
I am light handed with preload. I usually only go 1/2 to 3/4 turn.

Edit that. I just saw you are using hydraulic rollers. They normally like a little more preload. Maybe 1 full turn. I don't like going more than that on much of anything.
