The gt40p heads are based on the e7 design only opened up, your gaskets appear to belong to a Ford Yates* racing head . The first pic I found of the gt40p head, the exhaust is a symmetrically even spacing with all bolt holes in one line. The second pic is the Yates heads, highly sought after and well worth the money if you can get them if horsepower is what you want.

* Ford Yates racing heads are found on stock cars and will out flow even the Cleveland heads while using the larger valves. Capable of supporting 1000 horses naturally aspirated.
