The Cometic C5456-086 is a Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chrysler LA small-block V8 engines. This precision-manufactured gasket features a 4.180-inch bore diameter and a compressed thickness of .086 inches (approximately 2.18mm), making it ideal for performance builds and high-compression applications.

Key Features:

• Multi-Layer Steel (MLS) construction provides superior sealing and durability under extreme cylinder pressures
• 4.180-inch bore diameter accommodates stock and slightly overbored Chrysler LA V8 engines
• .086-inch compressed thickness allows for fine-tuning compression ratios in performance builds
• Embossed stainless steel layers with Viton rubber coating ensure maximum combustion sealing
• Designed to withstand high heat and pressure in boosted and naturally aspirated applications
• Compatible with Chrysler 273, 318, 340, and 360 cubic inch LA-series V8 engines

Cometic MLS gaskets feature multiple layers of stainless steel with strategically placed embossments that provide localized pressure for exceptional sealing around combustion chambers, coolant passages, and oil return holes. The advanced MLS design allows the gasket to recover and maintain seal integrity through repeated heat cycles, making it a premium choice for street performance, racing, and forced induction applications.
