I don't trust those books at all. Chiltons is better than haynes tho. I've found numerous errors in both. If in doubt, crack open the GM shop manual.

One full turn is the factory setting, puts the lifter plunger mid-way in its travel.
Higher RPMs can be had with less preload, but it really isn't an issue below 5500. I still set mine at 1/4 turn.
