1968 Barracuda Notch - Plano, TX

Really nice setup.
Less opportunity to make a mistake or maybe it's more accurate to say that by using this mounting system you are assured of it performing the way it should.
I no longer have my Roadrunner, but
I used the American Powertrain kit, and the issue I still have lingering questions or doubts about is the air gap (or lack thereof) between the tips of the diaphragm spring and the surface of the hydraulic throwout bearing.
If anyone sees any flaws in the following, please correct them:
With a mechanical TO bearing, there has to be an air gap between the diaphragm spring or the bearing spins constantly and no gap also makes it more difficult for the input shaft to disengage from all forces trying to make it spin.
The hydraulic TO bearing from what I was told more than once is designed to very gently ride on the tips of the diaphragm spring, thus always spinning, which is NOT OK with a mechanical TO bearing.
One of the advantages of this I was told is far less to no "lag" between the mechanical input (pushing on the clutch pedal) and the clutch reacting to being pushed on compared to a mechanical TO bearing.
My concern was by not having a gap it would mean wearing out a rather expensive bearing.
I'll stop there and end with a question:
Are hydraulic TO bearings supposed to have an air gap between the bearing face surface and the pressure plate spring tips OR is it supposed to gently ride on the spring tips?
This old can of worms was opened because I see making adjustments to the clutch hydraulic cylinder, actuating rod, and the components attached to it being easier or at least more precise by using the pedal mount bracket setup than the "pick a good spot" and install these couple of components and then hope they all work well where you put them" method.
