Cometic Chevy Gen1 Small Block V8 .030in MLS Cyl Head Gasket-4.135in Bore-With Edelbrock RPM Heads

When you're rebuilding the top end of your Chevy Gen-1 Small Block V8, getting the cylinder head gaskets right is crucial for a solid seal. This Cometic Multi-Layer Steel (MLS) gasket is specifically made for engines running Edelbrock RPM heads and features a 4.135-inch bore, sized at 0.030 inches undersize to ensure a precise fit. It’s designed to handle the demands of high-output engines, whether you're pairing aluminum heads with an aluminum block or cast iron block.

What makes these MLS gaskets stand out is their construction. They're built with multiple layers of stainless steel, which gives them strength and the ability to rebound, helping to resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. The center layer is also stainless steel, and its thickness can be varied to meet different sealing requirements, like the 0.036-inch compressed operating thickness you get with this gasket.

Because they're made with this advanced multi-layer steel construction and Viton coating, these gaskets seal exceptionally well without needing any extra sealants. This makes installation cleaner and helps ensure a reliable seal for your engine build. This gasket fits a wide range of vehicles from the early 80s, including models like the Chevrolet C10, Camaro, and GMC C1500.
