Product Details

The Cometic C5691-036 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Buick Stage I and Stage II V6 engines. This high-performance gasket features a 3.860-inch bore diameter and 0.040-inch compressed thickness, making it ideal for performance builds and engine rebuilds requiring precise sealing and durability.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 0.040-inch compressed thickness for precise compression ratio tuning
  • 3.860-inch bore diameter designed for Buick Stage I and Stage II V6 applications
  • Embossed stainless steel layers with Viton rubber coating for exceptional sealing
  • Resists blowout and withstands extreme cylinder pressures
  • Reusable design allows for multiple installations when properly handled

Cometic MLS gaskets are the preferred choice for performance and racing applications where reliable sealing under high boost, nitrous, or naturally aspirated conditions is critical. The multi-layer design allows the gasket to conform to minor surface imperfections while maintaining consistent clamping pressure across the entire sealing surface.
