What years were heads cast without "Ford" and "Made in USA" on them?
Dennis, Maryville Tn
I think they said "Ford" from start. "Made in USA" was added 04-16-12 according to the encyclopedia, and in August 1926 both texts were removed from the head castings. http://www.mtfca.com/encyclo/E.htm#eng3
Canadian heads may have been cast without the "Ford" text at other times: http://www.mtfca.com/discus/messages/179374/210502.html?.
