This precision gasket features a .044" compressed thickness and is designed for engines with a 4.220" bore diameter, making it ideal for performance builds and engine rebuilds requiring precise sealing.

Key Features:

• MLX Construction: Multi-layer design with integrated stopper layer provides superior combustion sealing and prevents head lift under high cylinder pressures
• .044" Compressed Thickness: Allows fine-tuning of compression ratios and deck clearances for performance applications
• 4.220" Bore Diameter: Round bore design accommodates standard and slightly overbored small block Chevy engines
• 18/23 Degree Head Compatibility: Engineered for both 18-degree and 23-degree aftermarket cylinder head configurations
• Integrated Steam Holes: Includes steam vent passages for proper coolant circulation and head temperature management
• Premium Materials: Constructed from high-grade stainless steel with advanced coatings for maximum durability and reusability

Cometic MLX gaskets utilize multiple layers of stainless steel with a stopper layer embossed around the combustion chamber to create a gas-tight seal. This design excels in high-performance and racing applications where traditional composite gaskets may fail. The gasket's construction allows for optimal clamping force distribution while maintaining flexibility to accommodate minor surface imperfections.

This gasket is compatible with Chevrolet Small Block V8 engines including 262, 265, 267, 283, 302, 305, 327, 350, and 400 cubic inch displacements when bored to the appropriate specifications. Ideal for street performance, racing, and engine rebuilding applications requiring precise head sealing and compression control.
