Have you ran this car hot at any time???
Its is unusually for the head gaskets to go in a 3800.... I'd drain all of the oil, and pull the lower intake...I'll bet money that you'll find bad lower intake manifold gaskets...

Also, the car has 130K on it and most likely hasn't had the UIM replaced.
Bonnevillebabie, take a look at this TECHINFO article.
Upper Intake Manifold Failure
Likely, you need to do both the UIM and the LIM gaskets replacement.

Hard to say based just on your limited description of the problem, but it is likely a main culprit at least. With the UIM bad and leaking LIM gaskets, your car will run like crap, keep getting worse, and if you don't fix it soon, could (in an extreme case, it'* happened before) cause hydrolocking of the cylinders and engine damage.
For sure you want to read all the info I referenced above, plus any LIM gasket replacement threads (do a search), then do that work if needed, before you go much further with anything else, IMO.

UIM in his case is the Supercharger, however, the LIM gaskets were prone to leaking on these cars.

If you are going to go through the H*** of pulling the motor, pull the lower intake and see if the gaskets are shot... They can easily leak coolant into the motor and create what looks like a blown head gasket... Check those gaskets before you doom the motor... Drain the old oil... Go to Wally Mart and get a cheap Supertech Filter and 5 qts of Supertech oil... Start the car and let it idle for a couple of minuts to get all of the bearings clean... Coolant in the oil can be hard on the bearings...
How long have you had this problem?

If yall could help that would be great

As far as cleaning the engine compartment, I would do that before starting all the work. Particularly before all the hoses and stuff are exposed. If it'* as dirty as you imply, use a heavy foaming engine cleaner and spray everything real well (it wouldn't hurt to cover the alternator and coils with plastic bags). Let set per the instructions on can, then hose off with garden hose. I wouldn't use steam cleaning or pressure washing personally. You can repeat if necessary and scrub any areas needing it with a brush. It really shouldn't take that long and will make it easier to work on the engine when you can see what you are doing.
After you are all done with your engine work and things are back in a buttoned up, you can do another quick cleaning. You'll be amazed at the difference.
Replacing the SC pulley has been done by many people here. Do a quick search here or wait for someone else to chime in.
