Looking over a cylinder head that I got from a friend today…I noticed the engineer/casting number to be 14 E BE-6090-BB. A quick comparison it to my D3 250 head with a micrometer…the valve size, combustion chamber and carburetor bore appears the same. Only difference I see different between the two is the vacuum port hole in the center of the log is larger and a boss casted between #1 and #2 intake runner which has a hex plug. Question is- What year head do I have? Could this odd casting number be designated to an industrial engine like an air compressor or pump? What’s up with the port on the front end of the intake?
