Howards max effort lifters

I am thinking about running these in my next super-stock engine and would like to know a little more about them. Howards web-site says you have to preload them .004" warm, how does one pre load a hydraulic lifter. Also has anyone ran these, any additional noise? thanks in advance, Clinto.:confused:

just like any other hyd lifter set at 0 and turn rocker nut use dial gauge on push rod side of rocker till it reads 004

but it says .004 warm, how do you set up cold for initial break-in.

block can grow .002 with iron heads so add .002 to .003 cold with iron heads about 005 with alum heads

Although I do not have hyd lifters it's always good to know these things.
Thanks to Pat and all the others that have knowledge they are willing to
share with us.
