Title: Cylinder head manufacture numbers Post by: fe350chev on June 09, 2013, 05:16:12 PM Can someone let me know if you can tell when a head was made or what model by its number. I know B designated numbers were for EJ blocks, but was wondering if anyone would know what a number: 7409457 head would have come off or whether its an FC head on the EJ block.

L = December 23 = 23rd day of the month 2 = year- this could be 1952 or 1962 depending on the number of water outlets.

It has b192 on side of the block. Didn't the EJ come out in July 1962?
I suppose the engines were cast and they the production process may have taken a bit to get going?doesnt b192 indicate it was 19 feb 1962? Why is the head red in colour?

It has a little gmh stamp on the corner top flange of the head?
