Do I need to adjust valves with hyd. lifters?

The type of lifter also makes a difference. If you have lifters with the very small wire clip retaining the plunger, then you need to adjust in a pretty good amount of preload, for instance .050"- .060". On the other hand, if you have lifters that use the heavy duty snap rings retaining the plungers, then you can use a liter preload such as .010"-.020". In fact, I prefer preload on the light side.
