Cometic GM LS1 SB 4.190in Bore .075in MLS Head Gasket

This listing is for one Cometic Multi-Layer Steel (MLS) head gasket designed for GM LS Gen-3 and Gen-4 small block V8 engines. It features a 4.190-inch bore and a .075-inch thickness, and it's coated on both sides with Viton for enhanced sealing. This gasket is built to handle the demands of LS engines, offering improved sealability, especially around the combustion chamber on open deck blocks thanks to its HP shim technology.

The Multi-Layer Steel construction provides a strong, reliable seal between the cylinder head and the engine block. The Viton coating on both sides helps create a robust seal against oil and coolant, resisting degradation from engine fluids. This gasket is a solid option for rebuilding or repairing your GM LS engine, ensuring a tight seal for optimal performance.
