A cautionary tale when working on push rods

HT-2011......
There’s no “R” in the part number, so they got the std wire clips.

I was referring to the Comp 867’s.
They’re “R” series(fast bleed) lifters.

The style of clip they use is to preload the position of the piston down about .030, so it’s in the correct position without adding any additional preload.
They’re designed that way to be run with essentially zero preload.
This is so if the valvetrain is run into a float situation, the lifter can’t pump up. It’s already “topped out”.

The downside is that clip design isn’t very robust and is easily damaged when the pushrods start dancing around.
