I just got the 2.1L liter engine I recently ordered for a customer. Not only
does it have a new case, but the heads look new also and they are not AMCs.
The casting includes POLAND right across the top. Not stamped but raised so
it was part of the casting. The hose connection on top is a slightly
different design. In stead of being part of the casting, it is a machined
sleeve pressed or glued or other wise attached for the hose connection. Oil
cooler and flywheel is there.
