    Percy's Seal-4-Good Reusable Flange Gaskets are multi-layered and made from a special "Dead Soft" aluminum that conforms to header flanges for the ultimate seal. Because made from multiple layers of dead soft metal, Seal-4-Good easily conforms to small imperfections that copper gaskets simply can't, and these gaskets will not blow out or burn out when properly installed.

    Rated 2 out of 5 by from Great if engine is on a stand my engine is in the vehicle. The gasket got caught on the header and tore in half. Left me with sheet of aluminum everywhere. Sure they work great if you have perfect amount of room to place them. Won't stand up to a little wiggling and catching though.
