4.125 MLS Head Gasket .060 - SBM

The 4.125 MLS Head Gasket .060 - SBM by Cometic Gaskets is designed specifically for small-block modified (SBM) engines that require precise sealing at the cylinder head. This gasket is crucial for builders and mechanics engaged in high-performance engine builds, restorations, or top-end rebuilds where standard gaskets may not suffice under increased compression or boost conditions.

With a thickness of .060 inches, this gasket is positioned to facilitate combustion chamber volume adjustments, making it essential for those combining cylinder head modifications with block machining. The MLS (Multi-Layer Steel) construction features layered steel with elastomer-coating, enabling it to endure elevated cylinder pressures while ensuring a reliable seal across various surface finishes.

Engine builders and performance shops working on street, strip, or off-road small-block platforms will find this gasket particularly beneficial, especially when paired with ported heads or stroker cranks. It is suitable for setups utilizing carburetors or fuel injection, especially those exceeding 400 horsepower, ensuring optimal performance and reliability.
