This is an interesting subject as to exactly when FORD changed the casting molds and did the later head carry the same CASTING I.D. NO. or was it superseded?

The '56 ECZ-C heads can have the plugs or not. Early had them. Late did not. So it occurred somewhere in the course of producing the '56 model year vehicles.
