Head Combo

Does anyone know what Mazda uses the next block / head combo?
The block has, on the left side, an area of BP 1 stamped on it, and head in the back (side distributor) BPO (or zero) 5-6-2 is a DOHC engine and I need parts, but need to know which cars have this combo.thanks all ....
BP engines were used Miata and protected. Since U have a dealer who kills the Miata as the source due to the fact that no distributor has ignited. I would say that sounds like 1996 to be used or protected which is not a 1.5 liter (which is the engine ZM). Use BP engine (I think it is a 1.8L and 1.6L)
