I think I remember the Renault design somewhere.

My rotary valving idea was just a shaft with notches cut into it that corresponded with ports in the head for exhaust and intake. RPM limited by the bottom end only and way less power to spin. Would shrink the heads to almost flat head specs.

Not as controlled as the video showed but rugged
