Cometic Honda H23A1 .120in MLS Cylinder Head Gasket - 87.5mm Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed stainless steel layers, featuring a Viton rubber coating on the outer layers. When compressed, it measures 0.036 inches thick, and it's designed for an 87.5mm bore. This gasket is a solid option for your Dodge Challenger, Charger, or Honda Prelude, especially if you're working with high-output engines where a reliable seal is critical.

The MLS construction offers increased strength and resilience, helping to withstand the forces generated between different block and head materials, like aluminum heads on cast iron blocks. The Viton coating on the outer layers is heat resistant up to 482°F (250°C), making it suitable for demanding sealing environments and various surface finishes. The center layer is stainless steel, allowing for different thickness requirements, like the .120 inch specification on this particular gasket.

Because these gaskets are designed for maximum sealing performance, they typically do not require additional sealants, simplifying installation. This makes them a popular choice for both aluminum-to-aluminum and aluminum-to-cast iron setups.
