it also works to silcone the gasket to the valve cover ,let it sit over nite ,then put a layer of silcone on the gasket and put on engin,,the heat shields are a good idea if you can find them or make them,,.dont scimp on the silcone,,its only about 2.99 for a cauking tube at menards or homedepo,,,,it wont burn off,,and its not the pretty blue stuff,,but it is the same stuff,,,GE or DAP or other brands,,,,..rick
