Cometic C5273-032 MLS Cylinder Head Gasket Chevy Small Block Bore - for V8 4.200

The Cometic C5273-032 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Chevrolet Generation 1 Small Block V8 engines. This gasket features a compressed thickness of .032 inches and accommodates a 4.200-inch bore diameter, making it ideal for performance builds and engine rebuilds requiring precise sealing and durability.

Key Features:

• Multi-Layer Steel (MLS) construction provides superior strength and heat resistance
• .032-inch compressed gasket thickness for precise combustion chamber volume control
• 4.200-inch bore diameter fits standard and slightly overbored small block applications
• Compatible with 18-degree and 23-degree cylinder heads
• Valve pocketed bore design prevents interference with larger valve configurations
• Integrated steam holes for proper coolant circulation
• Embossed stainless steel construction with Viton rubber coating for maximum conformability

Cometic MLS gaskets are manufactured using multiple layers of stainless steel, which allows the gasket to adapt to both head and block surface imperfections while maintaining excellent torque retention. The embossments on each layer provide micro-sealing around combustion chambers, oil passages, and coolant ports. This gasket is ideal for street performance, racing, and high-boost applications where reliability is critical.
