Default RS SOHC and WRX Intake manifold differences

What are the differences between the top feed Intake manifolds in regards to Injector spacing, diameters etc. Specifically will the After Market WRX fuel rails fit the RS Manifold using WRX Injectors

Looks like approximately 5 inches from center of back injector on pass side to center of front injector on same side. I'm guessing it would be the same for the driver side

They are the same size center to center. The manifolds bolt up the same The ports are located at the same spot and the injectors sit in the center. There will be no difference. however the rest of the manifold and sensors are very different.
