Cometic Chrysler B/RB V8 4.380in Bore .040in MLS Cylinder Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with a 4.380 inch bore and a compressed thickness of 0.040 inches, making it a solid choice for rebuilding or repairing Chrysler B/RB V8 engines. MLS gaskets are known for their ability to handle the high demands of powerful engines without needing additional sealants. They are constructed from multiple layers of stainless steel, which gives them strength and resistance to corrosion, while also allowing them to rebound effectively under stress.

The outer layers of this gasket are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating is designed to seal well in tough conditions and on various surface finishes, whether you're pairing aluminum heads with aluminum blocks or aluminum heads with cast iron blocks. The center layer is uncoated stainless steel, and its thickness can be varied to meet different sealing requirements. This construction helps manage the shearing forces that can occur between dissimilar block and head materials.

This gasket fits a wide range of Chrysler, Dodge, and DeSoto vehicles from the late 1950s through the late 1970s, including models like the Chrysler New Yorker, Dodge Charger, and DeSoto Adventurer. Always check the full fitment guide to confirm compatibility with your specific vehicle.
