Cometic Chrysler SB w/318A Heads 4.125in .060in MLS-5 Head Gasket Engine Quest HDS

If you're working on a Chrysler SB engine, specifically one with 318A heads and a 4.125-inch bore, this Cometic MLS-5 head gasket is built to seal things up right. It's designed for a compressed thickness of 0.060 inches, ensuring a solid seal for your engine build. This gasket fits a wide range of vehicles, including classic Mopar muscle cars like the Dodge Charger and Chrysler Cordoba, as well as trucks like the Dodge D150.

Cometic's Multi-Layer Steel (MLS) gaskets are a popular choice because they offer excellent sealing performance for high-output engines without needing any extra sealants. They're made from multiple layers of stainless steel, which gives them increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and different surface finishes. This construction makes them suitable for use with both aluminum and cast iron blocks, and they can handle the stresses that come from different metal combinations.
