4.410 MLS Head Gasket .060 - BBM

The Cometic Gaskets 4.410 MLS Head Gasket .060 - BBM (part number C5462-060) is a precision multi-layer steel cylinder head gasket engineered for Mopar B and RB-Series engines. This gasket delivers the sealing integrity required in high-performance and heavily modified engine applications where standard gaskets fall short. The 4.410-inch bore diameter and 0.060-inch compression thickness are optimized for increased displacement builds and boost applications, making this an essential component for engine builders targeting reliable cylinder sealing under elevated combustion pressures.

Cometic's multi-layer steel (MLS) construction provides superior gasket sealing compared to conventional composite designs. The 0.060-inch thickness accommodates custom head and block decking while maintaining proper combustion chamber volume and compression ratio targets. MLS gaskets are engineered to handle thermal cycling and mechanical load without creep, critical for turbocharged, supercharged, or naturally aspirated high-compression builds where traditional gaskets cannot maintain a dependable seal. The gasket's design integrates with Mopar big-block architecture to ensure proper clamping load distribution across the bore.

This gasket is intended for engine builders, performance shops, and restorers working on Mopar B-block (318, 340, 360 cubic inch) and RB-block (383, 400, 426, 440 cubic inch) engine rebuilds and upgrades. Proper gasket selection is critical when combining performance modifications—stroker kits, high-lift camshafts, ported heads, or forced induction—that increase peak pressure and engine stress. Each gasket is sold individually, allowing builders to purchase the exact quantity required for their specific project.
