Cometic C5692-030 Buick Stage I/II V6 MLS Cylinder Head Gasket .030 Thick

The Cometic C5692-030 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Buick Stage I and Stage II V6 performance engines. This gasket features a .030-inch compressed thickness and accommodates a 4.020-inch bore diameter, making it ideal for high-performance builds and forced induction applications.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• .030-inch compressed thickness for optimal compression ratio tuning
• 4.020-inch bore diameter accommodates stock and slightly overbored cylinders
• Engineered specifically for Buick Stage I and Stage II V6 engines
• Handles high cylinder pressures in turbocharged and supercharged applications
• Stopper layer design prevents gasket movement and ensures even clamping pressure
• Eliminates the need for sealants or re-torquing

Cometic's MLS gaskets feature multiple layers of stainless steel with advanced coatings that allow the gasket to conform to minor surface irregularities while maintaining excellent recovery characteristics. This design makes them particularly well-suited for aluminum heads and blocks where thermal expansion differences can challenge traditional composite gaskets.
