Shuebeck lifters?

They made solid lifters.
They are out of business for several years.
You can shim any of them to make the lifters solid easily.
I run them as shorten travel Hydraulics.
I never run them as solids = they have any clearance and
the bottoms have shattered and have turned $20,000+ engines into
junk in 30 runs. They need slight amount of preload to live and
can not do that if made solid.

Few stockers run them anymore except for me = i do not want to run
the new billet camshafts.
