How old is the clutch fork return spring? If that spring is worn, then the clutch fork may not be pulling the release bearing away from the pressure plate splines properly. Also, if the sleeve that the release bearing slides on is badly worn or grooved, then the bearing may bind and not slide back away from the PP splines. I would think that your transmission man would have mentioned a badly worn sleeve however. Also, as I understand it, Chevy mostly used 2 different sizes of release bearings over the years. Some refer to them as the tall and short versions. I imagine if you somehow got a tall version installed instead of a short version that you'd have a problem like you mentioned.

I recommend that you have a helper observe the movement of the clutch fork after you release the pedal to see if there is any delay or hang-up. If my hunch is correct, the PP tines push the release bearing away but it may still be making contact with the spinning tines if the fork doesn't pull it back another 1/4". Maybe all you need is a new clutch fork return spring.
