Nice buy that!
Be sure to get the supercharger's ceramic washers replaced ASAP. Even though they have nearly no hours on them, the things are still PITA's and need to be upgraded to steel pronto. You can do it yourself, it just takes and afternoon and about ~$120 or so for the washers and tool kit.
Finally take a few minutes to pull the valve cover off and inspect the top of the exhaust valve stems... some '06 4TEC engines still came with the hollow sodium filled exhaust valves, which are stamped on the upper portion of the stem with the number 72. You REALLY want exhaust valves stamped with the number 75 though, they are the upgraded solid stemmed valves. As long as this machine has sat unused I'd be concerned about corrosion on the hollow exhaust valve stems weakening them... it doesn't take much to cause the hollow stems to fracture.
Supercharger ceramic washers and checking out/replacing the exhaust valve stems should be the 2 highest things on your agenda for this machine before the weather warms up! With any luck, your valves will be the number 75 solid stemmed valves.
