1st gen is definitely on the right track. Does the Ferrea guy work there? If so he should know a few basics about 4 valve ports. One thing you do NOT want to do is knife edge the divider on the intake runner. It flows better when bull-nosed on the intake and knife edged on the exhaust - just like a plane rudder or a well prepped crankshaft. As for the valve job, if you'll study up a bit on your Bernoulli and do some testing you'll see that the air can't tell the difference between a radius and any number of angles under 15* difference between them so a radius valve job is typically no better than a good 3-5 angle valve job. Frankly, I don't see how you can run even a CORRECT 5 angle valve job on stock seats and get the right amount of space on the bottom cuts without going off the inside of the seat. Also keep in mind when talking about a 5-7 angle valve job how big the flats between the angles are going to be for optimal performance and the amount of space you need for the outer edge of the seat as well as keeping the seat height correct as well as keeping the venturi under the seat the appropriate size. Wait a minute nobody has mentioned the venturi yet...It's only one of the most important parts of the port besides the valve job so I can see why it gets missed (that must be because it is already too big from the factory)...BTW, I too love the Ferrea valves and have them on my own engine, but there are some great valves available from Kibblewhite and Manley. If I'm not mistaken there is some no-namer (Lisa Kubo I think was her name) running the Kibblewhite valves and seems to perform OK.
