Product Details
If you're working on a Chrysler B or RB V8 engine, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice for sealing your cylinders. It's designed with a 4.350 inch bore and a compressed thickness of 0.027 inches, making it suitable for a wide range of classic Mopar applications, from a 1959 Chrysler New Yorker to a 1978 Dodge Charger.
What makes this gasket stand out is its construction. It's built from multiple layers of stainless steel, which gives it strength and helps it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This combination ensures a strong seal, even with aluminum heads on cast iron blocks, and it doesn't require any additional sealants, simplifying your installation.
This gasket is a popular option for rebuilding or upgrading these classic V8s. Its robust design is meant to handle the demands of higher output engines, providing a reliable seal that can stand up to the pressures involved.
