Product Details

The Cometic C5478-080 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Ford 302 and 351W Windsor V8 engines. Designed for high-performance and racing applications, this gasket features a 4.030" bore diameter and .080" compressed thickness, making it ideal for builds requiring precise deck clearance and compression ratio tuning.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under extreme cylinder pressures
  • 4.030" bore diameter accommodates stock and slightly overbored small block Ford engines
  • .080" compressed thickness allows for precise compression ratio adjustment and deck height compensation
  • Compatible with Ford 302 and 351W Windsor small block V8 engines, including SVO variants
  • Engineered for high-performance street, strip, and racing applications
  • Resistant to blowout and combustion gas leakage even at elevated boost levels

Cometic's MLS gaskets feature multiple layers of stainless steel with proprietary coatings that conform to surface imperfections while maintaining excellent recovery characteristics. This design ensures consistent clamping pressure and reliable sealing across the entire combustion chamber, even in demanding forced induction and high-compression applications. Perfect for engine builders who need precision gasket thickness to dial in exact compression ratios.
