4.100 MLS Head Gasket .051 GM LS

The 4.100 MLS Head Gasket .051 GM LS from Cometic Gaskets is engineered for serious LS engine builders and performance enthusiasts who demand reliability in high-horsepower applications. This gasket is purpose-built for the General Motors LS platform, which is known for its performance and versatility in various automotive applications.

Cometic's multi-layer steel (MLS) construction utilizes a proprietary design that combines elastomer layers with solid steel shims, providing superior gasket conformability and sealing performance across varying clamping loads. The .051-inch thickness is specifically designed for the 4.100-inch bore diameter, making it suitable for both stock and performance builds. MLS gaskets excel at managing thermal cycling and resisting deformation under sustained boost pressure.

This gasket is ideal for applications ranging from stock rebuilds to high-performance turbocharged or supercharged engines. Its construction allows it to self-conform to minor surface variations, reducing the risk of gasket failure during peak combustion events, making it a reliable choice for any LS engine project.
