3.950 MLS RH Head Gasket .027 Dodge 5.7L Hemi

The 3.950 MLS RH Head Gasket .027 Dodge 5.7L Hemi from Cometic Gaskets is engineered for serious Mopar Gen III Hemi engine builders and enthusiasts who demand reliable combustion sealing. This cylinder head gasket serves as the critical barrier between the cylinder head and engine block, preventing coolant and oil crossover while maintaining compression integrity under sustained high-RPM operation. Whether you're rebuilding a stock engine, upgrading to performance specifications, or replacing a failed OEM gasket, this Cometic solution delivers the precision fit and durability required for long-term reliability.

Constructed from multi-layer steel (MLS) construction, the 3.950 MLS RH Head Gasket features a 0.027-inch compression thickness specifically calibrated for your 5.7L Hemi's combustion chamber geometry. The MLS design uses alternating layers of steel and elastomer to distribute clamping load evenly, reduce hot spots, and prevent gasket creep even under extreme cylinder pressures. The 3.950-inch bore diameter matches your Hemi's cylinder specifications precisely, while the right-hand (RH) designation ensures correct fitment on the passenger-side cylinder head. This engineered thickness maintains proper compression ratio and combustion efficiency, critical factors in both stock and modified applications.

Engine rebuilders, performance shops, and Dodge truck and car owners with 5.7L Hemi engines will find this head gasket essential for any top-end rebuild or head gasket replacement service. Proper installation requires torque-to-yield head bolts and OEM torque specifications, making this suitable for professional machine shops and experienced DIY builders familiar with Mopar Gen III protocols. Cometic Gaskets' reputation for precision manufacturing ensures compatibility with both OEM cylinder heads and aftermarket aluminum head options engineered for the 5.7L platform. For long-term durability and leak-free performance, this gasket meets the sealing demands of street, truck, and competition applications.
