Dual Spark plug 308/wide block,aluminum cylinder Head

A one off, 3 inch thick,dual spark plug 308/ wide block cylinder head from a running engine .I dont know much about it;I got it from a guy who got it in a batch of engines from an estate sale.It was in a group of diesel race engines from a land speed record racer out west,California i believe. The buyer did not know about Hudson flatheads....I bought two engines and 4 crankshafts from him.He originally listed these and other items on another forum and a couple of people called him a scammer.I called him and found him to be quite the opposite. Anyway its well designed by someone, if u know, let me know....im looking for $1000 plus shipping to lower 48...im near the beach in Florida Panhandle...come pickup if u wish.Thanks
