FWIW I make my own "solid" lifters. Take an old lifter, remove the clip, stuff a nut or similar object in place of the collapsible part, put it back together.

I also paint them orange so I know never to use them for anything else. Like you'd grab an old lifter out of a drawer when building an engine... but still.

I also use my kids' PlayDoh instead of modeller's clay. So you can "make" some of this speciality stuff yourself.

I also use the solid lifters when degreeing the cam and checking for coil bind, just to make sure the hydraulic piston isn't "cutting me any slack", as it were.
