Is the Permatex you refer to a black gooy dope? It is usually labeled as aviation grade...that stuff often ozes and runs down the sides of your newly painted block. We use no sealer what-so-ever and have zero problems. The copper gasket is designed to crush down into position (hence the rule to never re-use) and should seal perfectly if block face and head are true.
