The pontiac dealership has the following:
Red sealant for the SC reassembly (gasket maker)
SC outlet gasket (the big one)
Yellow O-ring coolant seals (between the SC and lower intake)
Fuel Injector O-ring kit
Get the coupler from ZZP.
If your dealer doesn't have that stuff, they're lying. Plain and simple. They want you to haul your car in. Go to the parts counter with this list. The parts are cheap. This list is also in the sticky in Forced Induction, with some of the part numbers.
