Cometic Chevy Gen-1 Small Block V8 4.200in Bore 18/23 Degree Head .051in MLS Cylinder Head Gasket

Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.051". With Steam Holes. Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements. Chevrolet Gen-1 Small Block V8 .051in. MLS Cylinder Head Gasket; 4.200in. Bore; 18/23 Degree Head; Round Bore; With Steam Holes

• The embossed outer layers of the gaskets meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes
• The center or shim layer is an uncoated stainless steel layer which can be varied to accommodate multiple thickness requirements
• Requires less clamp load creating less bore distortion
• Conforms load distribution across the sealing area
• Embossed Outer Layers Coated w/Viton

The Cometic Gasket Chevy Gen-1 Small Block V8 MLS Cylinder Head Gasket is engineered for high-performance engines requiring reliable sealing with minimal distortion. Constructed from multiple embossed layers of stainless steel, this gasket features outer layers coated with Viton rubber, providing excellent resistance to heat and harsh sealing environments up to 482°F. The gasket's compressed operating thickness of 0.051 inches ensures optimal fit and sealing integrity for high-output applications. Designed specifically for 4.200-inch bore engines with 18/23 degree heads, it is suitable for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks, accommodating various engine configurations. The gasket's multi-layer design enhances strength, rebound, and corrosion resistance, ensuring long-lasting performance under demanding conditions. Its embossed outer layers meet the demands of diverse surface finishes and load conditions, while the uncoated stainless steel shim layer can be adjusted to meet different thickness requirements. Unlike traditional gaskets, this MLS gasket requires less clamp load, reducing bore distortion and promoting even load distribution across the sealing surface. The inclusion of steam holes further improves coolant flow and helps prevent overheating, making it ideal for high-performance and racing engines. With no need for sealants, this gasket offers a clean, straightforward installation process, ensuring a dependable seal in high-stress environments and delivering consistent engine performance over time.
