Cometic C5485-086 MLS Head Gasket Ford Windsor Bore - 302/351W 4.200 086

The Cometic C5485-086 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Ford 302 and 351W Windsor V8 engines. This high-performance gasket features a 4.200-inch bore diameter and .086-inch compressed thickness, making it ideal for street performance and racing applications where stock gaskets fall short.

Key Features:

• Multi-Layer Steel construction provides superior sealing and durability under high cylinder pressures
• 4.200-inch bore diameter accommodates both stock and moderately overbored cylinders
• .086-inch (2.18mm) compressed thickness helps achieve optimal compression ratios
• Compatible with Ford Small Block Windsor (SBW) engines including 302ci and 351W variants
• Designed for use with SVO and other aftermarket aluminum cylinder heads
• Embossed stainless steel layers with multiple sealing beads ensure consistent clamping pressure
• Resists combustion pressure leakage, coolant seepage, and oil migration better than traditional composite gaskets

Cometic MLS gaskets are the preferred choice for engine builders working with forced induction, high compression ratios, or extreme performance applications. The multi-layer design allows the gasket to move with the engine's thermal expansion and contraction while maintaining an effective seal. Sold individually—two gaskets required per engine.
