4.165 MLS Head Gasket .080 - SBC

The Cometic Gaskets 4.165 MLS Head Gasket .080 for small block Chevy (SBC) is designed for engine builders and enthusiasts who require precise sealing in high-performance or rebuilt applications. This multi-layer steel (MLS) gasket is the industry standard for modern small block Chevy engines, ensuring reliable combustion chamber sealing where factory gaskets may not suffice.

The MLS design utilizes multiple layers of spring steel to evenly distribute clamping force across the sealing surfaces, which helps to prevent the brittleness and failure modes associated with traditional cork or asbestos gaskets. With a thickness of .080 inches, this gasket is engineered to match standard SBC block and head combinations, accommodating a 4.165-inch bore diameter for most SBC cylinder configurations.

This gasket is particularly beneficial for high-performance SBC applications, providing essential sealing for preventing coolant leaks and combustion gas escape. Proper surface preparation and correct head bolt torque sequencing are crucial for maximizing gasket longevity and performance in various SBC builds.
