Indeed, that was the accepted method on some V8's.  The adjustment was on
the pivot (so didn't jump around like a Triumph's adjustment will); and the
proper adjustment was to back off the nut until the valve clattered
(indicating the hydraulic lifter was at the end of it's travel), then
tighten it some specified number of turns.

There were special clips you could buy to temporarily block off the oil
holes, but most people just let it fly.
