SBF MLS Head Gasket 4.180 Bore .0425

The SBF MLS Head Gasket 4.180 Bore .0425 from FEL-PRO is designed for small-block Ford enthusiasts and professional builders seeking reliability in both high-performance and stock-restoration applications. This multilayer steel gasket is crucial for sealing combustion pressure between the cylinder head and engine block, ensuring consistent thickness under extreme thermal and mechanical stress.

Constructed from multilayer steel (MLS), this gasket offers superior performance compared to traditional cork or composite options. The 4.180-inch bore diameter is precision-engineered to fit standard small-block Ford cylinder heads, while the .0425-inch thickness is optimized for proper clamp load distribution and sealing across combustion chambers and coolant passages. MLS gaskets are particularly effective under boost, nitrous, and high-RPM conditions due to their resistance to deformation.

This head gasket is ideal for those installing a new short-block, replacing a failed gasket, or completing a comprehensive engine rebuild. Its engineered surface finish works seamlessly with modern head and block deck surfaces, creating a reliable seal without the need for additional sealant. Whether you're working on a 302, 351W, or 347 stroker, this gasket ensures optimal performance and durability.
