3.950 MLS RH Head Gasket .040 Dodge 5.7L Hemi

The 3.950 MLS RH head gasket .040 for Dodge 5.7L Hemi engines from Cometic Gaskets is designed for builders and enthusiasts seeking reliability during high-performance modifications or engine rebuilds. This right-hand gasket is essential for creating a secure seal between the cylinder head and engine block, preventing combustion gas and coolant leakage under various conditions.

Cometic's multi-layer steel (MLS) design features spring-loaded stainless steel core layers with elastomer facing, which helps maintain clamping force across thermal cycles. The .040-inch thickness is suitable for use with properly resurfaced or new cylinder heads and blocks, ensuring correct combustion chamber volume and valve timing geometry. MLS gaskets are known for their durability, resisting blowout under extreme pressure while preventing micro-leakage during idle and part-throttle operation.

This gasket fits the passenger side of your 5.7L Hemi block, and a matching left-hand gasket is required for a complete set. It is compatible with various Dodge models, including trucks, Chargers, and Challengers, but users should verify specific compatibility with their vehicle's engine configuration.
