The system will then ask you to input the amount of planes you wish to divide the manifold side and
divided line into. This value will determine how many time the probe will step down to begin the digitizing
process. In this example we are dealing with an exhaust port for a big block Chevy. Five additional
planes should be sufficient for the first half of the port and five additional planes for the other half of the
port. The more planes you have the more accurate the port will be. However, too many planes may make
no more difference in the overall outcome than if there was a lesser amount. In other words, too many
planes may be “overkill” and hence time consuming and unnecessary. A good rule of thumb would be to
start out with approximately .500” of spacing in between planes throughout the port
