Description
A proper header gasket is critical to maintaining a reliable seal between your LS1 cylinder head and exhaust manifold—any leakage compromises both performance and engine longevity. Fel-Pro’s steel core laminate construction handles the extreme thermal cycling and pressure cycling of high-performance engines without gassing out or failing prematurely. This pair is engineered specifically for large race ports, ensuring a precision fit that won’t compromise flow or create hot spots.
