Product Details

The Cometic C5691-040 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Buick Stage I and Stage II V6 engines. This precision-manufactured gasket features a 3.860-inch bore diameter and a compressed thickness of .040 inches, making it ideal for performance builds and engine rebuilds requiring precise combustion sealing.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 3.860-inch bore diameter optimized for Buick Stage I/II V6 applications
  • .040-inch compressed thickness for proper deck height and compression ratio
  • Advanced embossment technology ensures even load distribution
  • Designed to withstand extreme cylinder pressures in performance applications
  • Reusable construction allows for multiple installations when properly maintained

Cometic's MLS gaskets utilize multiple layers of stainless steel with advanced coating technology to provide exceptional resistance to blow-out and coolant leaks. The controlled compressibility design accommodates minor surface imperfections while maintaining optimal clamping force across the entire sealing surface.
