Cometic Pontiac 400/428/455 V8 .060in MLS Cylinder Head Gasket - 4.160in Bore

Cometic Gasket is well-known for making solid sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. It’s built for Pontiac V8 engines like the 400, 428, and 455, featuring a 4.160-inch bore and a .060-inch compressed thickness. This gasket is designed to handle the demands of high-output engines, ensuring a reliable seal between your cylinder heads and engine block.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This coating is tough enough for various sealing environments and surface finishes, making it suitable for both aluminum-to-aluminum and aluminum-to-cast iron head and block combinations. The center layer is stainless steel and can be varied in thickness to meet specific engine build requirements, like the .060-inch thickness on this particular gasket.

This gasket fits a range of vehicles, including models like the Pontiac Firebird, Grand Prix, and LeMans from the late 60s through the late 70s. Because it's an MLS design, it doesn't require any additional sealants, simplifying installation.
