About this part

Product Details

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example for your Honda B-series engine build. If you're putting together a hybrid setup with a non-VTEC block and a VTEC head, this gasket is designed to handle that specific combination, ensuring a strong seal between your engine block and cylinder head.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion and withstand the forces between different metal types like aluminum heads and cast iron blocks. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C), making it suitable for demanding sealing environments. The center layer is uncoated stainless steel, and the overall compressed thickness of this gasket is 0.040 inches, with an 84mm bore size, making it a precise fit for your hybrid B-series engine.

Because it's an MLS gasket, it doesn't require any additional sealants, simplifying installation. This makes it a solid option for both aluminum-to-aluminum and aluminum-to-cast iron engine configurations.
