4.100 MLS Head Gasket .060 - Dodge 6.1L

The 4.100 MLS Head Gasket .060 - Dodge 6.1L from Cometic Gaskets is a precision-engineered cylinder head gasket designed specifically for Mopar Gen III Hemi applications. Built for enthusiasts and professional mechanics who demand reliability during high-performance builds, this multi-layer steel gasket seals the combustion chamber under extreme pressure and temperature cycles. Whether you're rebuilding a 6.1L Dodge engine for increased horsepower, recovering from head damage, or performing a complete engine refresh, this OEM-quality replacement ensures a leak-free seal that holds up to boost, nitrous, and aggressive tuning.

The gasket features a 4.100-inch bore diameter matched precisely to Hemi cylinder specifications and a 0.060-inch compression thickness that maintains proper head-to-block sealing geometry. The multi-layer steel (MLS) construction provides superior durability compared to conventional composite gaskets, resisting blow-by and maintaining integrity under repeated thermal stress cycles common in modified engines. The MLS design also accommodates modern honing techniques and tighter machining tolerances, preventing premature failure from micro-leaks that plague older gasket designs. At 1.22 lbs, this gasket integrates seamlessly into your engine assembly without compromising structural balance or installation sequence.

Dodge 6.1L engine builders—from street performance applications to competition builds—rely on this Cometic gasket for consistent head sealing during reassembly. Proper installation requires careful surface preparation of both cylinder head and block, light torque in a star pattern, and inspection of existing head bolt condition; worn fasteners can compromise gasket clamping force and cause leakage. This gasket is ideal for anyone restoring a Dodge Charger, Challenger, or Ram 6.1L engine, as well as swappers installing Gen III Hemi cores into non-OEM platforms. The 0.060-inch thickness is critical—verify your engine's deck height and head-gasket surface condition before purchase to ensure correct compression ratio and fit.
