It appears there is a butterfly valve in the intake port on the head. Is this something that made it to the production engine? I see no mention of it in my '92 FWD service manual. Is that, or was that supposed to have been an actively tuned intake manifold (i.e., closing off one intake port per cylinder at low RPM for high swirl, opening it at higher RPM.
