Is there a part number or number prefix on the heads anywhere?
The Ford USA throws me here...the British marked lots of their 21 stud '37 heads like that with the firing order boxes (they made the '37 engine into the early 1950's) but they were all EnFo with an E at beginning of part number.

I have one just like it. Found it in a Kansas junkyard several years ago. Its a 37/38 21 stud. I thought it was unique enough at the time to spend 1 1/2 hours and two busted knuckles to pull it off the crusty engine. The firing order diagram was only on one head (I believe it was the drivers side). I'll look for a part number on it tonight.

During the 1960's Ford Parts Obsolete of Los Angeles (later Long Beach) imported a large number of 21 stud flathead engines that had been rebuilt by the British Military for their use. There were also a large number of flathead parts. If I remember correctly the heads came through with these markings. I have one of these engines in my '37 Coupe. Although I doubt it is true today I still hear rumors about warehouses of NOS parts in England. These stories seem to pop up every time someone places a "wanted" ad for parts.

British built only the 221 1937 type, but the imperial armies also used vast quantities of Canadian and USA 24 stud engines of both sizes...I think Carpenters NOS engines are built form Indian Army stashes of Canadian parts.
From memory, the Briish heads that Joblot imported in huge quantities were all British marked, I think E77 prefixes.
These heads are obviously USA and carry a pure USA prefix, and they are different form the 77 prefix heads that would have come on a 1937 truck...the normal head lacked that firing order box.
The regular 77 heads are common because they were used to replace all the rotted out 1937 78 passenger car heads...
These must surely be later replacement castings, but I have never seen any such aside from the British ones!

I took a look at mine after I got home this evening. It has the same PN as 51 merc - 77B-6050. It also has a casting code/date on the block side of the head, just below the water outlet of J214. Bruce - can you decipher that for actual casting date??

It is my understanding that this particular head was issued by Ford as a replacement for the 37-38 engines. The original heads did not have the firing order on them. I have a Canadian Ford publication [I know- the head in question clearly states Made In USA], called Fast Moving Parts Catalogue. Page 144 clearly shows this very same head configuration, and is described as:77 6050 Head-cylinder-RH & LH-cast iron[type 3], used Pass and trucks-except 60 HP, also bus 37. Brian
