Does anyone have any experience with Magnum MaxDry gaskets? I am looking into replacing the valve cover gaskets on the GP and RockAuto lists a MaxDry set (including grommets) that is priced just lower than the Victor Reinz and Fel-Pro sets. The slight price difference is not my main interest in them, but there is a good chance they are made in the USA (they claim 90% of their products are engineered, manufactured, and packaged in the US) and I thought I'd give them a shot if others have had good experiences. There is only one review for my product on Amazon and their complaint is that some of the grommets ripped during install.
