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 SVO, or classic hot rod, this gasket is engineered to withstand sustained boost, elevated cylinder pressures, and aggressive ignition timing that modern fuel and tuning packages demand.

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 optimized for 4.100-inch bore applications, ensuring proper clamping load distribution and preventing head lift during high-load conditions. MLS gaskets excel in forced-induction and nitrous oxide applications because they maintain sealing integrity under the extreme pressure spikes that blow past conventional gaskets, while the steel composition resists corrosion from coolant additives and extended storage.

This gasket is purpose-built for small-block Ford SVO (Special Vehicle Operations) and aftermarket stroker combinations with 4.100-inch bore dimensions, making it ideal for serious engine builders planning head upgrades, valve work, or long-block assembly. Proper installation requires clean, flat mating surfaces and correct head bolt torque specifications—typically 65–75 ft-lbs in a three-step pattern for maximum seal reliability. Whether you're freshening a tired 302, building a 408-cube stroker, or assembling a vintage race engine, Cometic's proven gasket technology ensures you won't chase coolant leaks or compression loss down the road.
