rockauto, the magnum lower intake gasket kits comes with the most extra parts and is the same upgraded metal gaskets. its like 42 shipped with a 5% off code.
that being said, the supercharged engines don't suffer the same fate as the na engines upper intake failing and eating coolant.
in your case before you spend money, pull the plugs, crank the engine over, if coolant comes out its likely a head gasket, if nothing comes out, do a compression test. if theres a bad head gasket this test will tell you.
