He is going to the trouble of creating that sweet ITB intake, it would make sense to match a big cam and badass heads for it. In the total cost of the build, its money WELL spent.

Can you setup those weber carbs for E85? Is it available in your area? if so I would think about making it run really high compression ratio's for it if its available in your area? It would help you make more torque down low, easier to tune on, run cooler, and all around just be perfect for a build like this.
We have 105 octane E85 at most every station in town, and it's roughly 40-50 cents cheaper than 93. The carbs can be set up for it pretty easily, there are alot of VW guys running it. It doesn't get as much mileage, but its alot cheaper so it works out to be fairly even, plus you get the benefits you mentioned. That isn't something I've thought about but is worth considering.
