Cometic C5461-092 MLS Cylinder Head Gasket 4.380" Bore .092" Thick Chrysler B/RB V8

Cometic C5461-092 Multi-Layer Steel Cylinder Head Gasket for Chrysler B/RB V8

The Cometic C5461-092 is a premium multi-layer steel (MLS) cylinder head gasket engineered for Chrysler B and RB V8 engines, including 361, 383, 400, 413, 426, and 440 cubic inch applications. This high-performance gasket features a 4.380-inch bore diameter with a compressed thickness of .092 inches, making it ideal for both stock rebuilds and modified performance builds.

Multi-Layer Steel Construction

Constructed from five layers of stainless steel, this MLS gasket delivers superior sealing performance for high-output engines. The stainless steel composition provides exceptional strength, corrosion resistance, and the ability to rebound under extreme conditions. The outer layers are embossed and coated on both sides with FKM (Viton) rubber material, which is heat resistant to 482°F (250°C) and designed to withstand harsh sealing environments, varying load conditions, and different surface finishes.

Advanced Sealing Technology

The gasket features controlled embossments that distribute clamping load evenly across the sealing surface, requiring less clamp load than conventional gaskets and minimizing bore distortion. A PTFE topcoat provides additional resistance to fretting and improves cold sealing capability. This design creates a micro-seal for fluids against both the cylinder head and engine block surfaces, ensuring reliable performance in both aluminum-to-aluminum and aluminum-to-cast-iron applications.
