I find it hard to believe that a DOHC head is near the same size as a OHV. One of the problems with the 4.6 Ford was the port was low and did not flow well, the fix was to raise the port which increased head size, as in the design the cams sit above the valve which sit above the port. It is much easier to get increase port flow with OHV by raising the port.
