It is a good observation as I'm sure you're very knowledgable on flow characteristics but I feel like this is the best design for the application. The OEM manifold is similarly designed just a smaller plenum. There are also aftermarket manifolds available very close to it that have been flow tested with nice gains. But good eye! Never really thought about it until now.
