Cometic GM LS1 Small Block 4.060in Bore .051in MLS Head Gasket

The Cometic H1518051S is an engine head gasket designed for GM LS1 small block engines. It features a Multi-Layer Steel (MLS) construction with two viton-coated outer layers and a steel inner layer, providing support and durability. This gasket is ideal for use with aluminum heads on cast iron or aluminum blocks and withstands significant shearing forces.

With a bore size of 4.060 inches and a thickness of 0.051 inches, this gasket is sold individually. It requires less clamping force, which helps reduce bore distortion. Once torqued, the gasket takes a set, eliminating the need for re-torquing.
