4.060 MLS Head Gasket .051 - SBF

The Cometic Gaskets 4.060 MLS Head Gasket .051 - SBF (small block Ford) is a precision multi-layer steel cylinder head gasket engineered for small block Ford engines requiring exact bore and compression specifications. This gasket delivers the sealing integrity demanded by both stock and modified engine builds, where proper compression thickness directly impacts combustion efficiency and preventing coolant or oil leakage between the cylinder head and block.

The .051-inch compression thickness is critical for maintaining correct combustion chamber volume and ensuring optimal compression ratios in small block Ford applications. Cometic's multi-layer steel construction provides superior durability under elevated temperatures and pressures compared to traditional gasket materials, making it suitable for daily drivers and performance-oriented builds alike. The 4.060-inch bore diameter is machined to exacting tolerances, ensuring compatibility with overbored or bored-to-size small block Ford cylinder heads. This gasket is designed as a single-use component—proper installation torque specifications and head surface preparation are essential for reliable sealing.

Small block Ford cylinder head gasket replacement is routine maintenance for engine rebuilds, performance modifications, and repair of existing cooling or oil leaks. Whether you are reconditioning a stock 289 or 302 engine, stepping up to a stroker configuration, or restoring a classic performance block, the correct compression thickness and bore diameter are non-negotiable. Cometic's reputation in the gasket and sealing industry makes this component a trusted choice among machine shops, engine builders, and serious enthusiasts who demand reliable OEM-quality or better sealing performance without compromise.
