Cometic Oldsmobile 330-455 V8 106.68mm Bore .098in MLS Head Gasket

If you're rebuilding the top end of your Oldsmobile 330-455 V8, or any of the many compatible Buick, Cadillac, Chevrolet, or GMC V8 engines from the 70s and early 80s, a good head gasket is crucial for sealing combustion. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the pressures of high-output engines and is designed to provide a reliable seal without needing additional sealants.

Cometic constructs these gaskets using multiple layers of stainless steel for 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 with different block and head materials, including aluminum to cast iron. The compressed thickness of this gasket is 0.098 inches, and the bore size is 106.68mm (4.200 inches), making it suitable for a wide range of V8 applications from the era.

This gasket is a solid option for engines that have been modified for more power or for a stock rebuild where a dependable seal is a priority. It's designed to fit right and perform well, ensuring your engine's combustion chambers are properly sealed.
