Sounds like the rings aren't seating, or the ring gaps weren't offset. It could also be to big of a crank for the motor. Some of the companies out there resleeve the block to accommodate the larger crank, to short of a sleeve can also cause some pretty bad piston slap.
After every rebuild I've seen or done, the engine always burns oil for the first couple miles or so until the rings seat to the cylinder.
