Re: Cylinder head marking
Castings were made under contract by different foundries after model a production ended.A number of different foundry marks have been identified,the 'diamond' mark is highly prized with engine blocks.Are there any other markings? Ford script is another indicator of a service head (heads produced for service after 1931) .The one in the picture shows a 1936 service head I have..its a high quality casting,clearly better than a production head. The L286 casting mark above the water pump boss indicates it was cast 12/28/36
