Permatex is generally not recommended for use on modern head gaskets, as many are designed to be installed dry without additional sealants. However, some older engine designs or specific gasket types might benefit from a thin layer of Permatex or another sealant to ensure a proper seal. It's crucial to follow the manufacturer's instructions for the specific gasket and engine type you are working with.
