Without doing the research, and from observation of the pictures provided, it becomes obvious that the sand casting molds that made these heads originated with a cast iron Ford Script head. Those with any degree of sand casting mold experience can substantiate this from the pictures alone. This fact in itself proves the heads to be a low budget ripoff product. I would think them to be of wall hanger value.
Going off your first sentence this is merely just your opinion and nothing more. No research and going off a picture does not determine these to be wall hangers. I find no value to your opinion and comment.
Here is a pair on EBAY that seller claims NOS.They are new but no Script but a 77- part number
Same as the heads there were on the engine in the '37 I once owned. I believe the were British manufactured.
