Description
A reliable header gasket is critical to maintaining combustion chamber integrity and preventing exhaust leaks that compromise performance and fuel economy. The Fel-Pro 1438 uses a proven steel core laminate design that resists blow-out under sustained high RPM operation, ensuring your LS1 exhaust system seals properly from initial installation through thousands of miles. This is a genuine OEM-specification gasket that won’t require re-torquing or replacement after the first heat cycle.
