Cometic C5506 Chrysler LA MLS Cylinder Head Gasket Bore - V8 4.030

The Cometic C5506 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered for Chrysler LA small-block V8 engines. This gasket features a compressed thickness of .040 inches and is designed for engines with a 4.030-inch bore diameter, making it ideal for stock and mildly overbored applications.

Key Features:

• Multi-Layer Steel (MLS) construction provides superior sealing and durability under high compression and temperature conditions
• .040-inch compressed thickness for precise compression ratio tuning
• 4.030-inch bore diameter accommodates stock and slightly overbored cylinders
• Designed specifically for Chrysler LA-series small-block V8 engines (273, 318, 340, 360 cubic inch)
• Stainless steel construction resists corrosion and withstands extreme cylinder pressures
• Embossed sealing beads around combustion chambers and fluid passages ensure leak-free performance

Cometic MLS gaskets are the preferred choice for performance engine builders due to their ability to maintain a reliable seal in demanding applications including street performance, racing, and turbocharged engines. The layered steel design allows for thermal expansion and contraction while maintaining constant sealing pressure across the entire head-to-block surface.
