Cometic Pontiac 400/428/455 V8 .060in MLS Cylinder Head Gasket - 4.410in Bore

When you're rebuilding the top end of your Pontiac V8, getting the cylinder head gasket right is crucial for a strong seal. This Cometic Multi-Layer Steel (MLS) head gasket is built to handle the demands of performance engines, offering a compressed thickness of .060 inches and a 4.410-inch bore diameter, specifically designed for Pontiac 400, 428, and 455 cubic inch V8 engines.

Cometic's MLS design uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes, making these gaskets suitable for both aluminum and cast iron blocks. Because they're designed for maximum sealing performance, these gaskets don't require any additional sealants, simplifying installation. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .060 inches found in this particular gasket.

This gasket fits a range of classic GM vehicles, including models like the Pontiac Firebird, Grand Prix, and LeMans from the late 60s through the late 70s. It's a well-built component that helps ensure your engine rebuild is sealed up tight and ready for the road.
