LS7 lifter preload

Is anyone running .100" preload on these? What is the average?

.045 to .060 for me and that makes me feel good. i would think .100 is absolute max.

I ran my LS1 lifters (same design) at 0.125" without issue although I wasn't wholly comfortable with that.

i run mine at .040 with no problem, I read on here that they max out at like .140 and running them at half that is normal, so .070 would be normal preload, mine sound good at .040.
