Just to put things in perspective, I recently purchased a set of eight 51 gram tool steel solid lifters from a small German manufacturer for my next air-cooled VW engine build and paid $468 for the set.
You gotta pay up for the good stuff.
I know they’re not hydraulic but these could be an option for those who don’t want a roller lifter but want a flat tappet lifter that’s not soft.
