The mazda part numbers for VVT heads are BP6D-10-100 and BP6D-10-100A (after 2/02). I can't find any changes in parts that occurred at the same time. I have seen where Mazda created an "A" part number when they moved to a different supplier for supposedly the same part (built to same specs, but often at a reduced cost).

Was at a friend's house today. He had two BP6D complete engines in his garage. One was marked BP6D-1-3 and the other BP6D-2-1
I wouldn't be surprised if it were something simple like year of manufacture and plant of origin or similar.
