Oilrag to adjust hydraulics usually you back off the nut until you can start to hear the rocker and pushrod tapping away. Slowly tighten until the noise subsides and that gives you your zero setting. Now SLOWLY turn about 1/4 turn at a time until your at your adjustment. I dont know what the setting is for these so I cant tell you if it is 1 1/2 turns??? I know a SBC is about 1/2 - 1 turn depending on who you ask.

I was never answered before, but isnt setting valves on solid lifters with the engine running asking for trouble???

Thanks, Jeff
