Review on Spectre Performance 5264 Valve Cover by Andre Bennett

This is the worst set of valve covers I have ever received. The stock rocker arms hit hard on the inside of the valve cover on both the intake manifold side and the exhaust manifold side. Start the engine and it sounds like Dam Ro Knock. You can see the notches made by the rocker arms on either side inside the valve cover. I will never buy them again. I'll discuss this with Specter and Revane. I have compared them to my bearings and there is one major difference between them.
