Question on port matching

Rat Bastid said
Ive already said it. NONE. Never make the port in the manifold smaller than the head. Ever. I realize you have to change your thinking to get it, but it’s still the fact. Watch the Morgan videos. The last thing you want in any system is corners. The next worse thing is changes in section. And then a mismatch going with the flow.

Sorry man, your just confusing me. I feel like your flipping back and forth. You said you said it before, I must have missed it. Now your saying none but earlier you were saying there has to be some because of the gain you say when there is with a larger port intake on a smaller head port.
