Supertech Honda B18A/B Non-VTec 82mm Bore 0.033in (.85mm) Thick MLS Head Gasket

This is a Supertech Multi-Layer Steel (MLS) head gasket specifically made for Honda B18A and B18B non-VTEC engines. It has an 82mm bore, which is the standard size for these engines, and a thickness of 0.033 inches (0.85mm). A good head gasket is crucial for sealing the combustion chamber, oil passages, and coolant passages between the cylinder head and the engine block. This MLS design offers improved sealing capabilities over older composite gaskets, especially under higher cylinder pressures.

MLS head gaskets are built from multiple layers of stainless steel with a special coating. This construction allows them to handle the heat and pressure found in performance or rebuilt engines better than single-layer designs. The precise thickness of this gasket is important for maintaining the correct compression ratio after installation. When you're rebuilding the top end of your B18A or B18B, a well-made head gasket like this one is essential for a reliable seal.
