Quote: 230 CC CNC -2 INTAKE PORT, keep in mind, if you've never seen these heads in person, for getting a feel for how big the 245 head is, a normal W2 head fully ported is in the 195 CC range. So the 230 CC Oval ICH is a BIG Oval, and the 245 rectangle dwarfs it. The actual minimum CSA of the 230 CC CNC -2 is 2.52" Someone wanted to know taht a few months ago, and I just got around to measuring it today. Thanks for the info. I guess I was pretty close Matt
