Here is a link to a post I made about the same issue with a picture.
5.9magnum questions
In the thread I mentioned that I only had the exhuast port issue with the MP R/T heads and not the factory heads my buddy had laying around. My issue was because the material around the port stopped just below the port, but the factory head was cast all the way to the deck surface and then machined. Not sure if this changed, but I assumed it wasn't an issue with any of the factory heads, only the aftermarket R/T head. Not sure what the EQ heads look like, either.
