4.100 MLX Head Gasket .051 - GM LS 6.2L RH

The 4.100 MLX Head Gasket .051 for GM LS 6.2L RH from Cometic Gaskets is purpose-built for high-performance LS engine builds and restorations. This multi-layer steel (MLX) head gasket is engineered for the right-hand (passenger side) cylinder head on 6.2L LS powerplants, making it essential for engine rebuilds, head work, or power upgrades. Whether you're restoring stock displacement or pushing into forced induction territory, a quality head gasket is the foundation of reliable compression and longevity.

Cometic's MLX construction uses multiple layers of spring steel with a proprietary elastomer facing to maintain a consistent seal under extreme cylinder pressures and temperature fluctuations. The .051-inch thickness is precisely engineered to achieve the correct combustion chamber volume and compression ratio for 6.2L LS applications, ensuring proper piston-to-valve clearance and thermal expansion stability. This gasket resists blow-by, prevents coolant intrusion, and handles the mechanical stress cycles inherent to both stock and modified engines without degradation, making it a trusted choice among serious LS builders and shops.

Mechanics and engine builders working on 6.2L LS platforms—from truck and performance car applications to crate engine swaps—depend on this gasket to seal reliably in both naturally aspirated and boosted configurations. Installation is straightforward when following proper torque sequences and head surface preparation protocols; always clean mating surfaces thoroughly and use the manufacturer's recommended fastener specifications. This right-hand gasket pairs with a matching left-hand unit for complete head gasket replacement, ensuring symmetrical sealing across both cylinder banks for maximum engine integrity.
