Cometic C5461-066 MLS Cylinder Head Gasket for Chrysler B/RB V8 4.380" Bore

The Cometic C5461-066 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chrysler B and RB series V8 engines. This gasket features a compressed thickness of .066 inches and is designed for engines with a 4.380-inch bore diameter.

Key Features:

• Multi-Layer Steel (MLS) construction provides superior sealing and durability under extreme cylinder pressures
• 4.380-inch bore diameter accommodates stock and slightly overbored applications
• .066-inch compressed thickness for precise deck height control and optimal compression ratio tuning
• Designed for Chrysler B-series (361, 383, 400) and RB-series (383, 413, 426, 440) V8 engines
• Embossed sealing beads around combustion chambers and fluid passages ensure leak-free performance
• Stainless steel construction resists corrosion and withstands high heat and pressure conditions

Cometic MLS gaskets are a popular choice for performance and racing applications where reliable sealing is critical. The multiple layers of stainless steel with elastomeric coatings allow the gasket to conform to imperfect sealing surfaces while maintaining excellent torque retention and reusability. Ideal for street performance, drag racing, and engine rebuilds requiring precise compression control.
