The Cometic C5633-060 is a Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chrysler LA V8 engines with a 4.040-inch bore diameter. This high-performance gasket features a .060-inch compressed thickness, making it ideal for engines with mild to moderate deck milling or applications requiring precise compression ratio adjustments.

Key Features:

• Multi-Layer Steel construction provides superior sealing and durability under extreme cylinder pressures
• .060-inch compressed thickness allows for compensation of deck milling and compression tuning
• 4.040-inch bore diameter fits standard and slightly over-bored Chrysler LA V8 engines
• MLS design eliminates the need for re-torquing and allows for minor surface imperfections
• Compatible with Chrysler 273, 318, 340, and 360 cubic inch LA-series small block engines
• Embossed stainless steel layers with elastomeric coating ensure consistent seal around combustion chambers, coolant passages, and oil return holes

Cometic MLS gaskets are a proven choice for performance and racing applications where reliability under high heat and pressure is critical. The gasket's multiple layer construction allows it to adapt to minor surface irregularities while maintaining excellent combustion sealing, making it suitable for both street performance and competition use.
