Cometic Ferrari F106A/F106B Dino V8 .060in MLS Cylinder Head Gasket - 89mm Bore

If you're rebuilding the top end of your 1959-1966 Pontiac Bonneville, this Multi-Layer Steel (MLS) cylinder head gasket from Cometic is a solid option. It's specifically designed for the F106A/F106B Dino V8 engine and features an 89mm bore with a .060 inch thickness. This gasket is built to handle the demands of high-output engines, offering reliable sealing without needing additional sealants.

Cometic's MLS gaskets are constructed with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material capable of withstanding temperatures up to 482 degrees Fahrenheit. This combination of materials ensures a strong seal, even when mating aluminum heads to cast iron blocks, and helps manage the shearing forces that can occur between different metals. The center layer is stainless steel and can be varied to achieve different thickness requirements, like the .060 inch on this particular gasket.

This gasket is a direct fit for several Pontiac models from the late 50s and early 60s, including the Catalina, Grand Prix, and Star Chief, in addition to the Bonneville. It's also listed for the Ferrari Dino 308 GT4. Ensure you have the correct bore size and thickness for your specific engine build.
