About this part

Product Details

If you're rebuilding the top end of your 1975-1978 Nissan 280Z or 1979-1980 280ZX, a reliable head gasket is crucial for proper engine function. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the demands of your L28 or L28E non-turbo engine, ensuring a solid seal between your cylinder head and block.

Cometic constructs these MLS gaskets with 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 and cast iron. This gasket is specifically sized for an 89mm bore and has a compressed thickness of .030 inches, making it a precise fit for your engine rebuild.

Because it's an MLS design, this gasket doesn't require any additional sealants, simplifying the installation process. It's a well-built component designed to maintain a strong seal under various operating conditions.
