What is the main advantage of a multi-layer steel (MLS) head gasket?

MLS head gaskets offer improved sealing capabilities under high compression and temperature conditions compared to older composite designs. Their layered construction helps maintain a consistent seal between the cylinder head and engine block, reducing the risk of leaks.

What does the 84mm bore and 0.030in thickness mean for my engine?

The 84mm bore matches the cylinder diameter for specific B20B engine applications, ensuring a proper seal around the piston. The 0.030-inch thickness is a common specification that works well with stock or slightly modified engines, contributing to reliable compression.

Does this head gasket come with any installation hardware?

This product is for the head gasket only. It is recommended to check the manufacturer's installation instructions for any required hardware or sealant, as head bolts and other components are typically sold separately.

Product Details

This multi-layer steel (MLS) head gasket from BLOX Racing is built with a 0.030-inch thickness and an 84mm bore, specifically designed to seal the combustion chamber in your B20B engine. MLS gaskets are known for their ability to handle higher compression and temperature changes compared to traditional composite gaskets, making them a solid choice for engine rebuilds or performance modifications where reliable sealing is critical.

The multi-layer construction uses stainless steel layers with a specialized coating to create a strong seal between the cylinder head and the engine block. This design helps prevent leaks and ensures consistent compression across the entire bore surface, which is important for maintaining engine performance and efficiency. It's a well-built component that aims to keep your engine running smoothly after a rebuild.

This gasket is a direct fit for several Honda and Acura models equipped with the B20B engine, making installation straightforward when you're working on your engine. Ensure your cylinder head and block surfaces are clean and flat before installation for the best possible seal.
