Exhaust Gaskets Chevy L6 OHV 216.5/235/261

The REMFLEX Exhaust Gaskets Chevy L6 OHV 216.5/235/261 (SKU REM2027) is a direct-fit graphite exhaust header and manifold gasket engineered for classic and vintage inline-six Chevrolet engines. This OEM-profile gasket maintains proper sealing at the exhaust manifold-to-cylinder-head interface, preventing exhaust leaks that degrade engine performance and fuel economy. Stock port geometry ensures compatibility with original equipment and most modern restoration builds.

Constructed from high-temperature graphite material, this gasket withstands thermal cycling and vibration inherent to engine operation without degradation or permanent set. The graphite composition provides superior resilience compared to standard asbestos or cork alternatives, making it a preferred choice for both stock and mildly modified applications. At 0.62 lbs with dimensions 5.1 x 0.45 x 34.35 inches, the gasket fits standard manifold bolt patterns across the 216.5, 235, and 261 cubic-inch displacement variants of the Chevrolet inline-six platform.

This gasket is intended for owners restoring or maintaining Chevy inline-six engines used in vintage trucks, cars, and marine applications where reliability and proper exhaust sealing are essential. Whether addressing a leaking original gasket or preemptively upgrading during an engine rebuild, the REMFLEX design delivers consistent performance without requiring torque specifications beyond stock fastener recommendations. Each gasket is sold individually, allowing users to service one cylinder head or purchase multiples for complete engine work.
