4.060 MLS Head Gasket .060 - GM LS1

The 4.060 MLS Head Gasket .060 - GM LS1 from Cometic Gaskets is a precision-engineered cylinder head gasket designed for GM LS-series engine rebuilds and performance applications. This component seals the critical interface between the cylinder head and engine block, preventing coolant and oil leakage while maintaining combustion chamber integrity. Whether you're restoring a stock LS1 or upgrading a performance build, a quality head gasket is essential for reliable engine operation and longevity.

Constructed from multi-layer steel (MLS) material, this gasket delivers superior durability and sealing performance compared to traditional fiber gaskets. The MLS design utilizes multiple embossed steel layers that create a resilient, conformable seal under extreme combustion pressures and temperature fluctuations common in modern LS engines. The 4.060-inch bore specification matches LS1 cylinder dimensions precisely, while the 0.060-inch compression thickness is engineered to maintain proper combustion chamber volume and static compression ratio without requiring head machining.

LS1 engine enthusiasts, rebuilders, and professional mechanics rely on Cometic's OEM-equivalent gaskets for stock restorations, turbo conversions, and supercharger installations. Proper installation requires clean, flat mating surfaces and recommended torque sequences specific to your engine block. This gasket is sold individually and is compatible with all 5.7L LS1 platforms, including Corvette, Camaro, Firebird, and truck applications. Always pair with a quality gasket sealer and follow manufacturer specifications for optimal performance.
