TorqStorm Supercharger build advice needed

Thanks. This makes me feel better. The plan is to get the engine yanked out this weekend or so and over to the machine shop. Even though the head was just done, it's coming back apart for the new valve springs that comes with the cam package and I'm going to have him do new valve guides. As far as I know, the engine (until we did the head) is untouched from the factory. Mileage is kind of unknown (there is some discrepencies) but based on the more reliable documents, I think it is around 150,000 or so. Odometer is around 50,000 and based on other wear when we first got the truck, I think it's 150 and not 250.
