Technical Help ID this cylinder head

I Googled the car. Those are "Maxi" heads. OHV exhaust valve heads for 21 stud flathead engines. Mostly used in trucks to help with the heat known to Ford V8 engines. Ed cast the valve covers himself. I guess Maxi never reappeared after the war.

 

Well now we know. I have always liked the car and the engine as long as I can remember.
Thanks for clearing that up. Good info.
