Spartan MLS Head Gasket SBC 4.067 Bore x .027

The Spartan MLS Head Gasket SBC 4.067 Bore x .027 from SCE GASKETS is a multi-layer steel cylinder head gasket engineered specifically for small block Chevy engines. This precision gasket maintains critical combustion chamber sealing across demanding operating conditions, delivering the reliability required in high-performance and street applications where engine integrity is non-negotiable.

Built with multi-layer steel construction, the 4.067-inch bore and .027-inch thickness specifications are engineered to handle sustained compression and thermal cycling without blow-by or coolant seepage. The precise bore diameter matches your small block Chevy block and head dimensions, ensuring zero-gap sealing at the combustion chamber perimeter. SCE GASKETS' MLS design uses microscopic surface finish optimization to create a reliable seal without requiring head surfacing, reducing machine shop costs while maintaining factory-level compression integrity.

This head gasket is ideal for engine builders, mechanics, and enthusiasts rebuilding or refreshing small block Chevy power plants—whether for street performance, bracket racing, or restoration work. The SBC platform remains one of the most versatile and frequently rebuilt engines in American automotive culture, and a quality head gasket is foundational to any build's longevity. The Spartan MLS delivers proven sealing performance without the premium pricing of exotic materials, making it the practical choice for serious builds on budget-conscious timelines.

Small block Chevy head gaskets are application-specific—bore diameter and thickness cannot be interchanged. Verify your block and head specifications before ordering. The .027-inch thickness and 4.067-inch bore are engineered for compatible SBC blocks and heads; mismatched parts will result in seal failure or compression loss. SCE GASKETS maintains consistent quality across its Spartan line, offering predictable performance whether you're running factory compression or ported heads with elevated boost pressures.
