The Cometic C5692-051 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Buick Stage I and Stage II V6 engines. This precision gasket features a 4.020-inch bore diameter and a compressed thickness of .051 inches, making it ideal for performance builds and rebuilt engines requiring reliable sealing under demanding conditions.

Key Features:

• Multi-Layer Steel (MLS) construction for superior strength and durability
• 4.020-inch bore diameter designed for Buick Stage I and Stage II V6 applications
• .051-inch compressed thickness for optimal compression control
• Excellent conformability to imperfect sealing surfaces
• Superior resistance to combustion gas leakage and coolant seepage
• Handles high cylinder pressures and temperatures in boosted or high-compression applications

Cometic MLS gaskets feature multiple layers of stainless steel with specialized coatings that allow the gasket to adapt to flange surface irregularities while maintaining excellent recovery properties. This design ensures consistent clamping pressure across the entire sealing surface, making them the preferred choice for performance and racing applications where reliability is critical.
