Port area isnt constant....
But think of it this way: air and fuel has momentum. It takes time to get it moving. Guys that port their stuff at home have a tendency to hog the ports out as big as they can, thinking a big port makes more power. In reality, a smaller port that flows the same as a big port will most likely perform better because the velocity of the charge will be higher and you can shove more in with respect to time.
Perfect scenario is a port that flows a lot, but is efficient enough to have high velocity as well.
