Cometic GM Dart/Brodix Small Block V8 .040in / 4.270in Bore / 4.500in Bore Center MLS Head Gasket

If you're rebuilding the top end of a Small Block V8 engine, especially one built for higher output, a good head gasket is crucial for sealing. This Multi-Layer Steel (MLS) head gasket from Cometic Gasket is designed to handle the demands of performance applications. It's built to seal effectively between aluminum heads and either aluminum or cast iron blocks, resisting the shearing forces that can occur between dissimilar metals.

This gasket features multiple layers of stainless steel for strength and rebound resistance, which also helps prevent corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well in various sealing environments. The compressed thickness of this gasket is .040 inches, and it's made with a 4.270-inch bore diameter and a 4.500-inch bore center spacing, making it suitable for Dart and Brodix cylinder heads. Because it's an MLS design, it doesn't require any additional sealants.

This gasket fits a wide range of vehicles from the early 1980s, including models like the Chevrolet C10, GMC C1500, and Camaro. It's a well-built component for engine builds where reliable sealing is a top priority.
