Cometic Chrysler 318/340/360 4.125in Bore .075in MLS-5 Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is designed for Chrysler 318, 340, and 360 cubic inch LA V8 engines. You get one MLS-5 head gasket with a 4.125-inch bore and a compressed thickness of 0.075 inches. This gasket is built with multiple layers of stainless steel for increased strength and rebound resistance, making it ideal for high-output applications. The outer layers are coated with Viton, a heat-resistant rubber material that ensures maximum sealing performance without the need for additional sealants.

These MLS gaskets are well-suited for use with both aluminum heads on aluminum blocks and aluminum heads on cast iron blocks, as they can handle the shearing forces that can occur between different metal types. The multi-layer construction provides a solid sealing surface that resists corrosion and can withstand demanding conditions. The center shim layer is stainless steel and can be varied to achieve different thicknesses, like the 0.075-inch on this particular gasket.

This gasket fits a wide range of Chrysler, Dodge, and even some Bristol vehicles from the mid-1960s through the early 1990s. It's a popular choice when rebuilding or upgrading the top end of these classic V8 engines.
