I guess I will go with Molina, for the head and exhaust gaskets. The head gaskets for the stock head don't really work with the 12 port, as the holes for the cylinders are really not comparable to the combustion chamber in the 12 port, and I don't really have the resources to make a nice sandwiched exhaust gasket the way they can. They are fairly cheap, (for a professional custom gasket) if anyone else needs custom gaskets.
