The spin the pushrod thing causes a LOT of problems for folks, the parts are oiled, you can still spin it with little to no resistance after zero lash. Zero lash is when the pushrod can't move vertically anymore.

not even close.....
maybe .1 of a turn.....bit not a whole 1/3 of a turn

if you get .3 of a turn from 0-22 ft/lbs...you weren't all the way down to begin with

With your definition of 0 lash I can see how you've come to that conclusion.

they actualy dont perform as well as the stock LS1 lifter did...
they were designed for the lightweight LS7 valve train....

but yes...as you said...keep the valve train light and they do just fine

better to throw in a set of Comp-R lifters or a set of Morels
