Cometic Buick Big Block V8 .030in MLS Cylinder Head Gasket - 4.400in Bore

Cometic Gasket is known for making well-built sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. It’s designed for Buick Big Block V8 engines and features a 4.400-inch bore with a compressed thickness of 0.030 inches. This gasket is built to handle the demands of high-output engines, ensuring a solid seal between your cylinder heads and block.

What makes this gasket stand out is its construction. It’s made from multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well in harsh sealing environments. This advanced design means you don't need to use any extra sealants, and it's effective whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as it can manage the shearing forces between different metals.

This gasket fits a range of Buick vehicles, including models like the Electra, Riviera, and LeSabre from the late 60s through the mid-70s. It’s a solid option for anyone rebuilding or working on the top end of their Buick V8.
