Cometic Pontiac V8 4.200 inch Bore .027 inch MLS Head Gasket

If you're rebuilding the top end of your Pontiac V8, like a 400, 428, or 455, a solid head gasket is crucial for sealing. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of performance engines, offering a reliable seal without needing extra sealants.

Cometic uses multiple layers of stainless steel for strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and various surface finishes. This design helps prevent leaks and withstands the forces created when mating aluminum heads to cast iron blocks, which is common in many Pontiac V8 applications. The compressed thickness is a precise 0.027 inches, ensuring proper compression ratios.

This gasket fits a wide range of Pontiac V8 engines from the late 60s through the late 70s, including popular models like the Firebird, GTO, and Grand Prix. It's a well-built option for anyone looking for dependable sealing in their V8 build.
