All, The whole thing about adjusting to 6 mils of lash was and is only a momentary (1/2 hour tops I believe) part of the "adjusting process". No one said (and if they did, they were wrong) to leave the valves at 6 mils of lash. It is just to get the lifters to pump full of oil before you adjust them back down 1 turn (360 degrees) from 6 mils, to allow the "hydraulic" part of "hydraulic lifters" to take over from there. Rich
