I have the Real Gaskets (post 57) T-stat silicone gasket on at least one of my Mopar V-8, plus their oil pan, valve cover, and tranny pan gaskets, basically any silicone gasket they have for mine in their catalog. I also use silicone heater hose in all my cars, silicone vacuum hoses, ... Did I mention I like silicone? Also silicone brake fluid, waterless coolant, stainless bolts and nuts. Polyurethane and butyl rubber are other materials that last.
