HEAD ID

Guest

I HAVE A 351C WITH HEADS STAMPED 4 IN THE CORNERS. I RECENTLY TOOK THE INTAKE OFF TO CHANGE AND MEASURED THE PORTS. THEY ARE ONLY 51MM INSTEAD OF 61MM. THE HEADS HAVE ADJUSTABLE ROCKERS. I THOUGHT THE 4V HEADS HAD THE 61MM PORTS AND NOT 51MM. THE MOTOR IS ALSO A 4BOLT MAIN. IS THERE ANY CASTING NUMBER THAT CAN ID THE YEAR OF THE HEADS?
