McGarrett - there is an interesting listing of cylinder heads located at https://www.fordgarage.com/pages/hea...ssionratio.htm. At first glance I don't see anything about the casting marks you show but there may be some other information there you can glean. A number of the aftermarket heads are noted to have "Made in USA" on them. The circle with dots is a code that many foundries use to indicate when the casting was produced.

I had a similar issue identifying an aftermarket head a few weeks ago and the Barners were really helpful. Hopefully someone here is familiar with what head you have. Good luck.
