The most important feature is the shape of the port and not it's size or intake runner size.We have learned over the yrs a good understand of a/f dynamics and how the shape of a port effects that and applying that to porting a head.That the cross section of a port is more important than the runner size.
That it takes time and experience to get it right and verification with a flow bench through trial and error. If you truly want to take it to the next level,do a search to start learning more.It is useless for you to have to go through the same things we did from the 50's to the 90's and then call it all good.
Maybe what bugs me the most,is a suggestion you ignore all during that time what we learned. That is maybe the single most important thing that has made such a huge difference from the very old school way of doing things.
