I keep learning but here is what I believe at this juncture:

A common manifold equal length system by its self can not stop cylinders from seeing exhaust pulse overlap on a 6 cylinder. --- It is mathematically impossible.

Equal length seems a solid improvement.

A fully split system seems a solid improvement.

Equal length with twin scroll turbine would seem even better.

Subject to there being an ideal split scroll turbo for one's goal and application.

Only if there there are divided wast gates and the turbo is a true split scroll design.
