Default Limited travel roller lifter setup

Butler set me up with a roller package that includes limited travel roller lifters.

The manufacture's lifter specs are .035" -/+ .010 preload. .035" would be about a 3/4 turn. Cam lift is .598" with 1.5 roller rockers.

Butler's site recommends starting at 1/8 turn for these lifters, which would be .006" preload. That is a wide range.

What am I looking for here...best vacuum, quietest operation.?

Currently I have set up at .025" preload (1/2 turn)..a bit noisy but performs well.
