Product Details

The Cometic C15551-040 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed for specialized Ford Windsor engine builds. This gasket is specifically designed to mate a Ford Boss 302 cylinder head (1969-1970) to a Ford 351 Cleveland engine block, enabling high-performance hybrid engine configurations.

Key Specifications:

  • Bore size: 4.150 inches
  • Compressed thickness: .040 inches (0.040")
  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • Compatible with RHS (Racing Head Service) aftermarket cylinder heads
  • Engineered for Ford Boss 302 head to 351C block applications

Features and Benefits:

  • MLS construction provides exceptional strength and reusability compared to traditional composite gaskets
  • Multiple layers of stainless steel with elastomeric coatings create a micro-seal that adapts to surface imperfections
  • Designed to withstand extreme cylinder pressures in high-performance and racing applications
  • Precision-machined bore dimensions ensure proper combustion chamber sealing
  • Ideal for custom engine builders creating Ford small block/Cleveland hybrid builds

Cometic Gaskets are a trusted choice among professional engine builders and racers for their consistent quality and performance in demanding applications. This gasket enables enthusiasts to combine the legendary Boss 302 cylinder head flow characteristics with the larger displacement of the 351 Cleveland block.
