[Ford blue blood]

When I was racing my Boss 302 the valve cover gaskets were rubber/cork. A small amount of Permatex was applied to the head surface, the gasket positioned, a light coat of white grease applied to the valve cover and torqued down. This arrangement kept the gasket from sticking to the valve cover, kept it in place with the cover off and had no leaks when in place when running. I even used this arrangement after putting the car back in "street trim".
