4.100 MLS Head Gasket .080 - SBC

The 4.100 MLS Head Gasket .080 - SBC from Cometic Gaskets is designed for small-block Chevrolet engines that require precise sealing at the cylinder head interface. This Multi-Layer Steel (MLS) gasket is ideal for both high-performance and street applications, ensuring reliable combustion chamber sealing that is essential for engine longevity and consistent performance.

With a .080-inch compressed thickness, this gasket provides superior crush and recovery compared to traditional graphite head gaskets. The 4.100-inch bore diameter is optimized for standard small-block Chevrolet cylinder head configurations, ensuring proper sealing ring coverage over each combustion chamber. MLS gaskets are particularly effective in modern engine builds, as they resist deformation under thermal cycling and maintain clamp load integrity across repeated heat cycles.

Mechanics and enthusiasts rebuilding small-block Chevrolet engines will find that this MLS head gasket performs exceptionally well with aftermarket aluminum cylinder heads, ported or resurfaced block decks, and in applications ranging from stock to high-performance setups, including turbocharged and supercharged configurations.
