The Cometic C5693-036 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 4.090-inch bore diameter and .036-inch compressed thickness, providing optimal sealing and durability for modified performance applications.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• 4.090-inch bore diameter accommodates stock and mildly overbored cylinders
• .036-inch compressed thickness for proper compression ratio and deck clearance
• Designed specifically for Buick Stage I and Stage II V6 performance engines
• Embossed stainless steel layers with Viton rubber coating resist high temperatures and pressures
• Eliminates head gasket failure common in high-performance applications

Cometic MLS gaskets feature multiple layers of stainless steel with precision-engineered embossments that create superior sealing pressure points. The Viton rubber coating ensures excellent conformability to imperfect sealing surfaces while maintaining resilience under extreme heat and combustion pressures. This gasket is ideal for turbocharged, supercharged, or naturally aspirated builds requiring reliable cylinder sealing.
