Cylinder head casting marks?

[Dan Partain]

I helped a friend with his model a and this is the head that was on it. I wasn't able to identify the maker. It looks like the same as you have.

Dan,
yep, looks like the same head alright. I do see a casting date tag under the distributor. I didn't notice it, but I'll check to see if mine has a date tag there too.

Some of those after market heads have the heart shaped combustion chamber of a high compression head.

Don't know how to tell from the outside.

Do a compression test.

I did find a casting date of 3-26-48. It would be interesting to know who made it. No Ford markings anywhere I can see.

I had a similar head, it is just a stock ratio aftermarket head. The casting marks fall into two categories: Long term mold charecteristics are alphanumeric or a dial indicator with nothing around them. Short term mold variables are made on a strip and riveted to the form the mold is made from, so even though it is cast, it looks riveted on. There were many makers of aftermarket A heads in the 40s.

Very interesting info - thanks for the reply.
