ive wondered about the tall and narrow ports myself? ive never seen a port that ur talking about but i know on the new vortec gm engines they are very very skinny but very tall also, i thougth maybe the thinness of them increased velocity but since they were so tall they still have some breathing ability to them, just my thesis. oh yea dont cut into about the vortec equipment, i just know this becuase i attend a GM sponsored school.
