GeeVee,

E 14 55

E = May
14 = 14 th day
55 = 1955

Did you look at the head under the edge of the valve cover to see if it has 4 screw/bolt holes for the stock valve cover?

Most likely someone put an old 216/235 2-bolt valve cover on your 1955 head (which I think matches the 1955 block your asked about in another post).
