4.060 MLS Head Gasket .051 - GM LS

The 4.060 MLS Head Gasket .051 for GM LS engines is a premium sealing solution tailored for high-performance and stock LS builds that require precise cylinder head to block isolation. This gasket is ideal for applications ranging from street engines to turbocharged and nitrous-equipped builds, ensuring reliable head gasket performance across various LS platforms.

With a .051-inch thickness, this gasket is engineered to optimize compression ratios and combustion chamber volumes, ensuring proper ring land clearance and head clamping force distribution. The Multi-Layer Steel (MLS) construction features spring-steel core layers laminated with elastomer coating, providing superior sealing integrity and resistance to compression set, which maintains effective sealing pressure throughout engine operating cycles.

This gasket is particularly beneficial for tuners and builders who need to accommodate head deck machining variations and block surface finishes while preserving compression ratios. The 4.060-inch bore diameter ensures proper flame-path sealing and thermal conductivity, critical for preventing coolant intrusion and maintaining cylinder pressure integrity under load.
