Hi Peter;
Thanks for describing what you show in the pictures, It's a big help.

Joe,
You are quite welcome. I find it most interesting to see something original and untouched and answering "those" questions we have all had about what should be. I am not a purist by any stretch but do like to have answers to my Qs.
I also noticed that there is evidence of a slight cleaning up around the inside of ports near the manifold that was likely done after casting to smooth them out. Looks like a larger burr type swirl.
Also the passenger rear corner has some surface grinding where I suspect the rough casting was poured, then ground smooth *after* the coating was applied, maybe caught during a final inspection. I verified my old heads had similar grinding marks, just covered with paint. Interesting this wasn't done before machining.
Anyway, glad to be of help!
Peter
