How do you replace a 1998 Porsche Boxter head gasket?

Replacing the head gasket on a 1998 Porsche Boxster involves several steps. First, disconnect the battery and drain the coolant and oil. Then, remove the engine covers, intake manifold, and other components obstructing access to the cylinder heads. Once the heads are exposed, unbolt them, remove the old gasket, clean the surfaces, and install the new gasket before reassembling everything in reverse order, ensuring all torque specifications are followed.
