Cometic Buick Big Block V8 .030in MLS Cylinder Head Gasket - 4.385in Bore

If you're rebuilding the top end of your Buick Big Block V8, getting the head gasket right is crucial for a strong seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of performance engines, ensuring reliable compression and preventing leaks.

Cometic uses multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes, meaning you don't need to add any extra sealants. This gasket has a compressed thickness of .030 inches and a bore size of 4.385 inches, making it suitable for a range of Buick Big Block V8 applications from 1967 through 1976, including models like the Electra, Riviera, and LeSabre. Its construction is well-suited for pairings of aluminum heads to aluminum blocks or aluminum heads to cast iron blocks.
