Pontiac Grand LeMans / LeMans 5.0L 1980, Seal-4-Good™ Exhaust Header Gaskets by Percy's High Performance®. The Percy's Seal-4-Good Reusable Flange Gaskets are multi-layered and made from a special "Dead Soft" Aluminum, which conforms to header flanges for the ultimate seal. Since the Seal-4-Good is made from multiple layers of dead soft metal, it easily conforms to small imperfections that a copper gasket simply can not. Due to this construction, these gaskets will not blow out or burn out when properly installed. This product is made of high-quality materials to serve you for years to come. Designed using state-of-the-art technology and with customers in mind. It will meet your needs and deliver great quality at an affordable cost.
