I agree with Jon, it looks as though the water passage is now at the top and the inlet ports have been lowered. Presumably this is too allow a better shot at the inlet valves whilst allowing a greater volume of water to pass throught the head.
I think the original Sport had the water manifold intregral with the inlet manifold rather than seperate as on all the other 20V models. However, everything else was in the normal place as far as i know, so that rules that out.
Looks as though there is a nice cast tapered plenum inlet in the background of the last pic. Certaintly very interesting, providing you can get the complete assembley, including valvetrain, valves, cams etc, even the inlet too. Trying to source replacements would be a nightmare considering that we don't even know what it is!
Whether it offers any real world advantage over a normal head is debatable. Perhaps the money would be better spent on overcoming some other barriers.
If we can get some shots of the inlet we might be able to tell the application.
Good luck with the negotiation.
