Cometic Oldsmobile 370/371 Gen1 Rocket V8 .040in MLS Cyl Head Gasket-4.190in Bore-J2 Golden Rocket

When you're rebuilding the top end of your Oldsmobile 370 or 371 Gen 1 Rocket V8, getting the cylinder head gaskets right is crucial for a solid seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of these classic V8 engines, ensuring a reliable seal between your cylinder heads and block.

Cometic uses 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 tough sealing environments and different surface finishes, meaning you won't need any extra sealants. The center layer is stainless steel and can be varied in thickness; in this case, it's set to provide a compressed operating thickness of 0.040 inches, with a bore size of 4.190 inches, making it a good fit for a range of Oldsmobile models from the late 1950s.

This gasket is designed to work well with both aluminum and cast iron blocks and heads, and it's built to withstand the forces created when different metals are joined. It's a well-built option for anyone looking to get their Rocket V8 engine back in reliable running order.
