Who regrinds the lifter face crown on used lifters

What is the general cost of lifter regrinds for a set of .842 flat tappet and who is recommended ?

I called Mizpah Precision Mfg and spoke with Kristin. I was quoted pricing starting at $2.50 to $4.00 a lifter. Kristin stated that the lifter is completely taken apart. The internals are kept with the main shell-body and cleaned in a sonic cleaner machine. Then the shell-body get a new spherical radius grind on the bottom. Sonic cleaned again then assembled.

Better take them up on it; they're losing money at that price for a hydraulic lifter.

I watched my boss when I was 18 yrs old take some stock lifters and regrind the bottoms on a Craftsman valve grinder and stick them in a 305 with a Comp 292 cam. Ran for yrs like that. Might of been he used stock springs and pressure lol that saved it.
