the opening of the intake port is machined larger to match the size of the oem 4V intake manifolds. That's the only difference.

I'll take a moment and make sure you understand the concept of a 3V port. The 3V port is 2V in size, but it is raised approx. 3/8" so that the roof of the port is the same height as the roof of a 4V port. If it were raised another 3/8", it would approximate the location of the ports in the C302 Ford Motorsport heads.
