Head Label
 

Does anyone have a guess as the origin of the head shown in the attached picture? One stamping/label says "MADE N U.S.A" and the other one says "2-28-33".

Thanks:

Could be any one of the various after-market foundries making replacement heads for the Model-A during the 1930's. Sears Roebuck, Montgomery Wards, Western Auto, etc. sold Model-A parts well into the 1960's.

Usually heads made after 1931 had these types of markings.

Just curious if it’s a high compression head?

Re: Head Label
 

my indication would be no as far as picture goes, But??

Re: Head Label
 

I don't actually know...never been off the engine during my ownership.

A compression check will let you know if the head is high compression or not. Add a little oil to the cylinders first to remove the rings from the picture. The stock head will produce about 50 psi and a high compression head about 90 psi.

Look at the front of the head, on the lip below the water outlet. Is there any markings on there?

Re: Head Label
 

No markings on the lip below the water jacket. Compression is around 50. So, unlikely that this is a high compression head.

Ford outsourced casting for the model A after regular production stopped and same with cylinder blocks. This is where the diamond blocks came in. They kept building the model A engines on a separate line till 1941 for agricultural products and industrial applications. The late B engines had the C head but even they eventually went out of regular production.

Most aftermarket heads were for higher compression applications.

I have one just like it except mine says 43 I think instead of 33. It is a low compression stock model A head.

I had one of those, very similar looks & date. My Dad had told me once it was a higher compression head because the chambers were more heart shaped than round? I didn't really need it so I let it go.
