I have a 1966 Buick 300 that I am reassembling. I am questioning the recommended sealing procedure for the intake manifold, thermostat housing, and carb gaskets. I have always been a fan of dry gaskets, but there seems to be much discussion out there recommending otherwise. The gaskets are Fel Pro and came with no manufacturer recommendation. My plan was to apply a thin film of Permatex Ultra Gray to both sides of the intake manifold gasket and the end seals. Same with the thermostat housing but using blue RTV on both sides of the gasket. The carb gasket I'm not sure as RTV is not good with gasoline. Any advice from previous experience would be appreciated. Thanks!
