Cometic GM Dart/Brodix Small Block V8 .044in MLX Cyl Head Gasket-4.310in Bore-4.500in Bore Center

If you're rebuilding the top end of your GM Dart or Brodix small block V8, especially an open deck block, getting the cylinder head gasket right is crucial for a solid seal. This Cometic MLX head gasket is built to handle the demands of these engines, ensuring reliable performance and preventing leaks.

This gasket uses Cometic's HP shim technology, which is designed to increase the clamping force around the combustion chamber. This means a tighter seal, especially important for open deck designs where the block walls are not fully supported. The outer layers are embossed and coated with Viton, a material known for its resistance to heat and oil, helping to maintain sealability under tough conditions. With a 4.310-inch bore and designed for a 4.500-inch bore center, it's made for specific performance applications.

This gasket fits a wide range of vehicles, including many Chevrolet and GMC trucks and cars from the early 80s, as well as models like the Avanti II and Excalibur Phaeton. Make sure to check the full fitment list to confirm it's the right part for your build.
