How do you figure out port center line length?

Is there an easy way to figure out port center line length?

Simple... measure the outer/long length then measure
the short length..divide by 2... that is all the way
to the seat... string works real well... tape it all the
way

If the head were chambers down. You're talking the floor and ceiling of the port?

Thanks! I purchased the program you mentioned. Very informative. A few things could be explained a little better. But all in all seems like a pretty good program.

I like all the header combinations it gives you and tells you what they should do in theory.
