Big horsepower 318 builds

hey guys, figured i would ask here rather than make a new post... My engine has magnum roller lifters, hardlan sharp (mancini) rockers.. i have been hearing a bit of lifter noise, not bad but i shouldn't hear any. Was curious if anyone knows how many thousandths 1 turn of a HS adjuster is for preload? I did a search but didn't find it..

Also, i believe preload should be .035? Can anyone confirm? If i had a couple with too much preload would they not pump up properly? the noise isn't even as loud as a solid cam, just annoys me i can hear it at all
