the one with the H's is an 81-85 engine, your picture isn't good enough, but an 81 engine has a screw in heater hose connection, the 82 has a pressed in barb and 83-85 have a T to use the beehive oil cooler
the other one is a 79 pr 1980 non California engine. 1980 California has an EGR valve on the top
the stamp is what Mazda used to do on rebuilds. around 1996-1997 they switched to a blue tag glued to the front cover.
