Cometic C5909-120 MLS Cylinder Head Gasket Ford Windsor Bore - V8 4.030

The Cometic C5909-120 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Ford Windsor V8 engines equipped with AFR cylinder heads. This precision-manufactured gasket features a compressed thickness of 0.120 inches and a 4.030-inch bore diameter, making it ideal for performance builds requiring reliable sealing under high-compression and high-boost conditions.

Key Features:

• Multi-Layer Steel (MLS) construction provides superior sealing and durability
• 0.120-inch compressed thickness allows for precise compression ratio tuning
• 4.030-inch bore diameter accommodates stock and slightly oversized cylinders
• Designed specifically for use with AFR (Air Flow Research) cylinder heads
• Embossed stainless steel layers with Viton rubber coating for maximum conformability
• Excellent resistance to blow-out and combustion pressure leaks
• Handles extreme cylinder pressures found in turbocharged, supercharged, and high-compression naturally aspirated engines

Cometic MLS gaskets are the industry standard for performance engine builds, offering the rebound characteristics and sealing properties necessary for demanding applications. The advanced material composition maintains seal integrity through repeated heat cycles while accommodating the thermal expansion differences between aluminum heads and iron blocks. This gasket is sold individually and requires proper surface preparation for optimal performance.
