Default Schubeck lifters

What's the proper break-in procedures for these lifters on a solid lift cam? Oil, rpms, spring pressure, etc.
This is my first times using these and I have been told that break-in is much like break-in using roller lifters, is that correct?

There is no break in procedure. But unless you have the full ceramic solids, I'd be very careful with the solid, or hydraulic ceramic bottoms. Cost me a good engine.

No break in proceedure, set the valve adjustment and run em.
Be aware if and when your engine is in valve float, and run enough spring pressure. Nothing wrong with these if you pay attention. Many racers run these for a long time with positive results.

Jim, as the other said no brake in necessary. What we did when we did a cam change was take a spring shim out, warm the car up a couple times, checking things as we went. Then installed the shims back in to put the seat pressure where it needs to be, then run it. I know these steps are not necessary but I was extra cautious. We run a sbc, hyd set up. I know it is a different combo, but we run shubecks.

I just had a Schubeck lifter loose it's puck, the engine got f**ked. Never put them in any engine again. Use tool steel lifters for now on.
