Cometic Pontiac 400/428/455 V8 .080in MLS Cylinder Head Gasket - 4.300in Bore

When you're rebuilding the top end of your Pontiac V8, getting the cylinder head gaskets right is crucial for a solid seal. This Multi-Layer Steel (MLS) gasket from Cometic is built for engines like the Pontiac 400, 428, and 455, featuring a 4.300-inch bore and a thickness of .080 inches. It's designed to handle the demands of higher output engines, ensuring a reliable seal between your cylinder heads and block.

Cometic's MLS design uses multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping to resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This construction means the gasket can be used with both aluminum and cast iron blocks, and it doesn't require any additional sealants, making installation more straightforward. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .080 inches on 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's ready to go for your engine build.
