Product Details
If you're working on a Chrysler B or RB series V8 engine, like those found in a 1970 Dodge Charger or a 1965 Chrysler Newport, this Multi-Layer Steel (MLS) head gasket from Cometic is a solid choice for sealing your cylinder heads. It's designed with a 4.250-inch bore and a compressed thickness of 0.027 inches, making it suitable for a wide range of classic Mopar applications.
This gasket is constructed from multiple layers of stainless steel, which gives it strength and helps it resist corrosion and deformation. The outer layers are coated with Viton, a heat-resistant rubber material that can handle high temperatures up to 482°F (250°C) and works well with different head and block materials, including aluminum to cast iron. Because it's an MLS gasket, it doesn't require any additional sealants, simplifying the installation process.
