As you can see we've corrected our port but it does remain and does work extremely well. Just because the port doesn't match the gasket doesn't mean the port is bad or too big. Do you know much about the NA heads? Short comings they have or what needs to be addressed? We've spent a considerable amount of time developing our ports. Sling shade all you want based on your personal viewpoint but in reality our stuff does work.
All of our porting is done CNC now so we can gain the best repeatability bearing the quality of the casting.
