Well (do not ever) spin the pushrod as you can preload the lifter all the way through its
travel and still spin the pushrod. the best way i have found on initial build is to have the
engine on the stand and run a pre lube tool with a drill to pump the lifters up and adjust
them with someone running the drill, this of course is after pre-lubing long enough to
get oil to the top on all cylinders. Once everything is pumped up use a .002 feeler gauge
to give yourself a little clearance between the rocker and the valve tip when running and pumped up.
