Description

The Cometic H4049SP5054S is a left-side head gasket designed for Gen III/Gen IV LS engines with a 6-bolt configuration. It features a 4.200-inch bore opening and a compressed thickness of .054 inches.

Constructed from multi-layered steel, this gasket utilizes MLX (Multi-Layer Stopper) technology. This technology incorporates an integrated stopper layer for effective combustion chamber sealing and enhanced clamp load around the cylinder without causing bore distortion. No sealants or re-torque are required after installation.
