Southbend clutch not disengaging

So I just installed a brand new southbend clutch in my 88 f350.

It wont quite disengage with the clutch with the pedal all the way down. The old clutch worked fine other than the dual mass flywheel distorying itself.. So i'm confused.

Anybody else have this problem? The only thing i can think of is the bushing between the clutch pedal and the master cylinder pushrod is worn out but thats only like a 16th of an inch..

Thanks in advance!

Master cylinder leaking down?

+1 Bleed it. Maybe some material worn from the seals in the master got pushed back when the clutch went in and is holding the edge of a seal open in the master.

Flex at the firewall? I've heard this can be a problem. Have someone look while you push.
