Re-using Used Lifters on Another Cam

Got the TShirt.

Some years ago I installed used solid lifters (from 2 different sets too), on a used hydraulic cam, and drove some 3+ years with that setup.
I figure-8 the lifters on fine emery paper, put paste on the cam, and some additional cam break-in additive in the API SJ oil and re-broke in the cam/lifters. No issues.

Would I do this when building an engine for someone else? No.
My own stuff when in a pinch to get it running quickly? Would probably again.

The important issue here is lifter-rotation.
