4.030 MLS Head Gasket .036 SBF

The 4.030 MLS Head Gasket .036 SBF by Cometic Gaskets is designed for small-block Ford enthusiasts who require dependable sealing in high-performance settings. This multi-layer steel (MLS) gasket is ideal for engine builders, mechanics, and tuners working on stock rebuilds, mild boost applications, or naturally aspirated performance builds.

Featuring a 4.030-inch bore diameter, this gasket is compatible with various Ford small-block cylinder head configurations. Cometic's MLS technology utilizes precision-stamped stainless steel layers bonded to a nitrile rubber facing, providing superior resistance to combustion pressure, thermal cycling, and coolant erosion compared to traditional cork or composite designs.

The .036-inch thickness is optimized to ensure proper head gasket crush without necessitating machining of decks or heads in standard applications. This gasket effectively seals on both stock and lightly ported cylinder heads, accommodating minor surface imperfections while retaining excellent clamping load even after multiple heat cycles, making it a reliable choice for street and light performance use.
