Cometic Buick Big Block V8 .074in MLS Cylinder Head Gasket - 4.400in Bore

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. Designed for Buick Big Block V8 engines with a 4.400-inch bore, this gasket is built to handle the demands of higher-output applications. It features multiple embossed layers of stainless steel, providing increased strength and resistance to corrosion, which helps ensure a solid seal over time. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F and works well with different block and head materials, including aluminum to cast iron. This gasket is designed to provide maximum sealing performance without needing additional sealants.

The multi-layer steel construction not only adds strength but also allows the gasket to rebound, helping it maintain a tight seal even under stress. The center layer is stainless steel and can be varied to achieve different compressed thicknesses, with this particular gasket having a compressed operating thickness of 0.098 inches. This makes it a solid option for rebuilding or upgrading your engine, ensuring reliable sealing for your Buick Big Block V8. It fits a range of vehicles, including models like the Buick Electra, Riviera, and LeSabre from the late 60s and early 70s.
