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.
