It's called the 'Bernoulli principle' or 'venturi effect'. In our cars PCV system, the intake port is designed thus as air flows both ways (to and from) the intake depending on engine RPM. This 'draw' is not to be confused with engine 'vacuum' in the manifold. But is can be useful in a catch-can setup when you want a small amount of 'draw' from the PCV valve (as an example).
P.S. what paint did you use on the intakes? They look very good!!!
