identifying 13b
It's a 6 port 13B from a 84-85 GSL-SE.
Old School pre-84 13Bs are 4 port. They do not have oil injectors and they have the old school "Mazda" logo on the housings.
As far as mounting any front cover will work the same, it's the cross mount that's diffrent from a 12A mount because the 13B is longer. If my memory serves me right 13B is 22MM longer.

That looks like a Turbo II oil fill, but there's no corresponding oil feed on the front end.
Pics of the ports side of the engine would be very helpful, That's where the magic is.
