4.100 MLS Head Gasket .080 GM LS

The Cometic Gaskets 4.100 MLS Head Gasket with 0.080 inch compression thickness is a multi-layer steel cylinder head gasket engineered specifically for GM LS-series engines. This precision-machined gasket maintains combustion chamber seal integrity under high heat and pressure, making it essential for both stock and modified LS builds where reliability and performance depend on eliminating compression loss at the cylinder head interface.

The 0.080 inch compression thickness specification is critical for LS-series gasket selection, as it directly affects final compression ratio and combustion chamber volume. Cometic's multi-layer steel construction provides superior conformability compared to traditional single-layer gaskets, allowing the gasket to seal irregular surface finishes while maintaining dimensional stability across thermal cycles. The 4.100 inch bore diameter fits standard LS cylinder head specifications. For engine builders and technicians, this gasket offers the durability and sealing performance required in both street and competition applications where head gasket failure can result in costly rebuild cycles.

This gasket is suited for LS engine rebuilds, performance upgrades, and routine maintenance where OEM-equivalent or upgraded sealing performance is required. Whether rebuilding a Gen III, Gen IV, or LS9 platform, proper gasket selection based on bore diameter and compression thickness ensures cylinder head gasket longevity and eliminates head gasket-related compression loss. Sold individually, allowing builders to purchase the exact quantity needed for their engine configuration.

Cometic Gaskets has established itself as a trusted OEM and performance gasket supplier, known for precision manufacturing and consistent quality across automotive, motorcycle, and powersports applications. LS engine builders recognize Cometic gaskets as a reliable upgrade path from factory gaskets.
