About this part

Product Details

If you're rebuilding the top end of your GM Dart or Brodix small block V8, getting the sealing right between the block and heads is critical. This Cometic Multi-Layer Steel (MLS) head gasket is built to handle the pressures and temperatures these engines can generate. It's designed for a 4.270-inch bore and features a 4.500-inch bore center, making it suitable for a wide range of V8 applications, including many from the 1980s like the Chevrolet C10, Camaro, and GMC C1500.

Cometic constructs this gasket from three to five layers of stainless steel. This material choice offers increased strength and resilience, helping it rebound and resist corrosion over time. The outer layers are embossed and coated with Viton, a high-performance rubber material that can withstand temperatures up to 482°F (250°C). This coating is key to meeting the demands of tough sealing conditions and varying surface finishes you might encounter during an engine build.
