About this part

Product Details

If you're rebuilding the top end of your Chrysler B/RB V8 engine, getting the head gasket right is crucial for sealing combustion pressure. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the demands of high-output applications, ensuring a solid seal between your cylinder head and block.

This gasket is constructed with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle harsh sealing environments and various surface finishes, making it suitable for both aluminum-to-aluminum and aluminum-to-cast iron head and block combinations. The compressed thickness is .027 inches, and the bore size is 4.500 inches, designed to fit a wide range of Chrysler B/RB V8 engines found in vehicles like the Dodge Charger, Chrysler New Yorker, and Dodge D100 Pickup from various years.

Because it's an MLS gasket, it doesn't require any additional sealants, simplifying the installation process. The layered stainless steel design provides the strength needed to withstand the forces generated in performance engines.
