SB Intake.

Locomotion said

That's a Tarantula intake. Suppose to be for higher RPM than a Torker.
A mismatch like that is nothing to be concerned about since the intake ports are smaller than the head ports.... But then one side would overlap without interfering with flow while the other would.

Locomotion sorta stumbled on the answer at the end.

Any mismatch causes flow interference. It is called a sudden expansion or sudden contraction which reduces flow energy. You will learn this if you take a fluid dynamics class. Totally smooth with minimum transition is the way to go.

This class will also teach you how to calculate Mach numbers which is the basis for ram induction and the cross ram design.
