On a dual plane, this would be alternating between planes so why would there be an issue?

When intake runners are designed, the location of the planes and fuel/air distribution of the intake are based on the firing order pulses, especially for torque and low end power. The runner length, size and height are not always the same on OEM dual plane intakes. A changed firing order also may effect the location of the primary tubes on the exhaust collector.
