SBF MLS Head Gasket 4.100 Bore .052

The FEL-PRO SBF MLS Head Gasket 4.100 Bore .052 is designed specifically for small-block Ford applications that require precise sealing and durability under high compression and aggressive tuning. This gasket is ideal for engine builders, performance mechanics, and automotive enthusiasts who are working on modified SBF platforms and need reliable cylinder head sealing across various thermal and pressure cycles.

Constructed from multi-layer steel (MLS), this gasket offers superior conformability and reusability compared to traditional composite gaskets. Its .052-inch thickness is optimized for common SBF deck heights and aftermarket cylinder head combinations, ensuring proper gasket crush and clamp load distribution across all eight cylinders. The advanced facing materials resist hot spots and prevent micro-seeping along the fire ring, maintaining integrity through sustained RPM operation.

This gasket is particularly beneficial for those running high-compression ratios of 11:1 or more, as well as turbocharged configurations where gasket failure can lead to catastrophic engine damage. It is compatible with both OEM and performance aftermarket cylinder heads designed for the 4.100-inch bore family, making it an excellent choice for a variety of builds, from stock rebuilds to high-performance applications.
