In no particular order.

1 bellhousing not aligned to block. Are the block and bell original to each other?

2. Pilot hole in crank not deep enough.

3. Sometimes rebuilt pressure plates are not set properly so that the plate is not parrelel to the flywheel causing one side to drag.

4. Pilot bearing might need to be reamed.
