Pedestal mount? I don't think it matters how many turns really (up to 1 full turn) as long as they're torqued down properly. Keep in mind that if they go over 1 full turn, you need shims. I think Michael Yount said .30 shim = 1/4 turn. Michael Yount has several posts in different threads regarding this subject, so maybe try an advanced search for "rockers" and his user name: Michael Yount.
