it depends. the valvetrain manufacturer should give a recomendation on valve lash. or you can adjust til quiet, but make sure not to over tighten.

You want to adjust the preload afte the car has run so the lifters are pumped up.
Take the load off the lifters, change your springs, then preload the lifters in sequence abou 1/2 to 3/4 a turn for a street motor.
What spring are you installing, and how is this motor run? Street, track, etc.
