    I can see running an oval port intake on a rectangle port head but not running rect intake to a oval head. Is there any threads showing this ?

    Actually you can't run an oval port intake on a rectangular port head, but you can run a rectangular port intake on oval port heads. Just make sure you use rectangular port gaskets.

    It's an old drag racers trick (before they started making good after market intakes for oval ports) to take advantage of the upper RPM's on the rectangular port intake and still keep the lower RPM torque of the oval port heads.
