good stuff terry!
though I would like to add a bit of commentary, for some of the folks out there
You need to remember, that things are all about balance, and intake ports (and exhaust ports) are no different in this regard. You need to determine what the ports you are considering need. Are they large enough? how is the port velicity? how much flow loss am I getting here?
Sometimes larger ports will help, sometimes they won't. An example, if you have a port that is perfectly balanced between it velocity profile and its flow volume, then larger ports will simply kill flow velocity, and reduce top-end power (maybe pick up a bit of low-end, but not always on that either) BUT if you have a port that has good velocity, but is actually restrictive to flow, then opening up the port a bit will probably increase flow w/ little to no decrease in velocity (or in rare cases my increase velocity)
It all comes down to the old adage, "measure twice, cut once" make sure you know what you are doing before you try to do somehting (unless you are experimenting, and can afford to screw up a few times)
It's all about balance. Look at everything as a system, and treat it as such.
