I'm still unclear on the difference between tunnel wedge and tunnel port. TP pics I've seen, the oval ports are huge and require matching intake\heads. I assume the tunnel wedge also requires matching intake\heads and the ports are larger than a high riser but smaller than a TP? Some pics of the intake ports would be nice (Wedge).

The TP has ports that flow around brass tubes housing the push rods. Not so with the Wedge?
