Product Details

When you're rebuilding a GM Dart or Brodix small block V8, getting the sealing right is crucial, and this Cometic MLS head gasket is built for that job. You get one multi-layer steel gasket, coated on both sides with Viton rubber. This gasket is designed for a 4.270-inch bore and has a 4.500-inch bore center, making it suitable for a range of classic American V8s from the early 80s through the mid-90s, including vehicles like the Chevrolet Corvette, GMC C1500, and Avanti II.

Cometic uses multiple layers of stainless steel for this gasket, which gives it strength and helps it resist corrosion while maintaining its ability to rebound under pressure. The outer layers are embossed and then coated with Viton, a high-temperature rubber material that can handle up to 482°F (250°C). This coating is key to meeting the demands of tough sealing conditions and varying surface finishes you might find on an engine block and heads.
