Head Porting

The image i used from phista is not of a port cut straight down the middle....that cut is off to one side of the port...that is why the line stops there...cause thats over the middle.
Straight up from the seat and laid back immediately and far back ,over half ways. I gave you guys valuable info...if you can understand and execute it accurately...see thats the hard part. When i ever do a head for one of you in this thread... youll see and have your moment of clarity.

LOL. Well, I'm not about port understanding. That's gonna be your job.
