If you back the adjustment off until the grind is gone at pedal to floor, does the unit work? Is shifting OK? That .060" gap is a starting point. It's not set in stone. A thicker clutch disc may cause you to run .030". A thicker disc will force the fingers deeper into the pressure plate as well, providing less clearance to disengage.
When it gets to where the clutch does not release and it still grinds the finger backsides you definitely have a problem.
