Hi All, I purchased NAPA (Fel Pro) VS50145R valve cover gaskets. They are stiffer than the typical rubber gaskets. These are considered 'premium' on the NAPA website. Attributes: Product Features:Increased Fluid Sealability. Material:Hi-Temp. Coated Fiber. http://www.napaonline.com/MasterPages/NOLMaster.aspx?PageId=470&LineCode=FPG&PartNumber=VS50145R&Description=Valve+Cover+Gasket+Set My problem is the valve covers have never leaked more since I put these gaskets on! >From the Fel-Pro site, I see they have several material listings, but none have the same wording as the NAPA site. http://www.federal-mogul.com/en/AftermarketSolutions/NorthAmerica/SealingSolutions/Products/LeakRepair/PerformanceValveCover/RubbercoatedFiber/ I used the sticky 'Permatex' material, cranked down the 6 bolts, not too tight to let the gaskets seat correctly. The service manual torque spec. was probably for 'cork gaskets'? They were easy to compress, but this material is like a 'hockey puck'. I have continued to torque the bolts down, working across the cover, and now I am almost where I fear I may break off the bolts. If anyone has used these gaskets or other ones that would work better, please make your suggestions. I tried to buy a premium product, but it has resulted in poor results. Before I tear it apart, I would like to hear some advice. Should I just go back to the standard rubber gaskets? Thank you, Mark Lindahl '63 300 Conv.
