Hi and thanks for using 2CarPros.
I checked for recalls or technical service bulletins and found nothing related to the head gasket. Before I would arbitrarily assume the gasket is bad, I would recommend testing. It isn't hard to do. Here is a link that shows how it is done:

Now, if you confirm the head gasket is the problem, here are the directions for replacement. All attached pictures correlate with these directions.

Installation
1. NOTICE: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges that make leak paths. Use a plastic scraping tool to remove all traces of the head gasket.
NOTE: If there is no residual gasket material present, metal surface prep can be used to clean and prepare the surfaces.
Clean the cylinder head-to-cylinder block mating surface of both the cylinder head and the cylinder block in the following sequence.
1. Remove any large deposits of gasket material with a plastic scraper.
2. Apply metal surface prep, following package directions, to remove any traces of oil or coolant, and to prepare the surfaces to bond with the new gasket. Do not attempt to make the metal shiny. Some staining of the metal surfaces is normal.
2. NOTE: Lubricate the bolts with clean engine oil prior to installation.
