The Fel-Pro 1142 PermaTorqueMLS engine cylinder head gasket is engineered to deliver reliable sealing performance across a range of GM V8 engines, including the 265, 283, 302, 307, 327, 350, and 400 cubic inch displacements. Crafted with proprietary multi-layer steel (MLS) technology, this gasket is designed to withstand high cylinder pressures and the dynamic movement of performance engine components. Its strategic sealing beads surround the combustion chamber and coolant passages, effectively concentrating clamp load to prevent leaks and ensure engine integrity under demanding conditions. Whether you're working on a rebuild or a performance upgrade, this gasket provides a durable, high-quality solution for imperfect sealing surfaces and dissimilar material interfaces such as aluminum heads on cast iron blocks. The Fel-Pro PermaTorqueMLS series is specifically engineered to simplify installation, fix common OEM design issues, and enhance engine longevity by maintaining sealing integrity even during significant scrubbing and movement. This gasket is not intended for use in emission-controlled vehicles, making it ideal for high-performance applications where maximum sealing and durability are critical.
