4.100 MLS Head Gasket .056 - SBF SVO

The 4.100 MLS Head Gasket .056 - SBF SVO from Cometic Gaskets is a precision-engineered component designed for small-block Ford enthusiasts and performance builders who demand reliability in high-revving engines. This multi-layer steel (MLS) gasket serves as the critical seal between your cylinder head and engine block, preventing coolant and combustion leakage while maintaining compression integrity. Whether you're rebuilding a street performer, track-focused vehicle, or classic hot rod, this gasket is engineered to withstand sustained boost, elevated cylinder pressures, and aggressive ignition timing.

Cometic's multi-layer steel construction delivers superior gasket sealing compared to traditional composition gaskets, with elastomer layers that conform precisely to head and block surfaces while resisting thermal cycling and chemical degradation. The .056-inch thickness is designed to provide optimal clamping load distribution, ensuring a reliable seal under high-load conditions. MLS gaskets excel in forced-induction and nitrous oxide applications because they maintain sealing integrity under extreme pressure spikes that can compromise conventional gaskets.

This gasket is suitable for small-block Ford engines, including aftermarket stroker combinations with 4.100-inch bore dimensions, making it an excellent choice for performance builds. Its robust design resists corrosion from coolant additives and extended storage, ensuring longevity and reliability. Whether you're a professional builder or a DIY enthusiast, this gasket will meet the demands of your high-performance engine.
