4.165 MLS Head Gasket .051 - SBC

The 4.165 MLS Head Gasket .051 - SBC from Cometic Gaskets is specifically engineered for small-block Chevy (SBC) engines, providing a precision cylinder head seal essential for high-performance builds, rebuilds, or stock restorations. This gasket is ideal for mechanics and engine builders who require reliability and durability in their engine assemblies.

Constructed from multi-layer steel (MLS), this gasket offers superior sealing capabilities compared to traditional composition gaskets. The alternating layers of stainless steel and elastomer create a conformable, reusable seal that effectively resists combustion pressures, coolant erosion, and thermal cycling. This design ensures proper sealing surface contact and consistent compression ratios across all eight cylinders.

Engine builders choose the Cometic MLS gasket for a variety of applications, from daily drivers and street rods to drag racing platforms and marine installations. Its layered construction maintains clamping load even under extreme conditions, preventing gasket creep and blow-by, making it a preferred choice for modified engines running boost, nitrous, or high RPM power levels.
