In some applications the throw out bearing always makes constant contact with the clutch fingers?

The application I’m building for my Superformance Cobra consists of a 351W based stroker with QuickTime bell housing, TKO600 trans and a slave cylinder that pushes the clutch fork forward to depress the clutch, as the clutch fork end mounts to a pivot point on the passenger side of the bell housing. I noticed that the slave cylinder inner spring always wants to push the internal piston forward and that when doing the initial install I have to overcome this spring resistance which pushes the piston back down into the slave cylinder. I’m pushing the piston back down into the slave about 2 inched or so and then locking the activation rod (coming out of the slave cylinder) against the clutch fork. This puts a small degree of pressure on the throw out bearing pushing it up against the clutch face or fingers which I suspect will keep the throw out bearing constantly engaged.
Is this typical for slave cylinder installations? I thought the throw out bearing was supposed to maintain a clearance away from the spinning clutch when in gear and between shifts? Perhaps this only applies to clutch pedal mechanical linkage hook ups?

Thanks in advance for any thoughts or advice on this.
