Cometic Toyota 3S/5S Hybrid 87mm Bore .040in MLS Head Gasket

This is the Cometic Toyota 3S/5S Hybrid Multi-Layer Steel (MLS) head gasket, specifically sized for an 87mm bore and featuring a .040 inch thickness. It's built for those undertaking a hybrid engine build using the Toyota 3S and 5S engine platforms. MLS gaskets are known for their durability and ability to seal under high pressure and temperature conditions, making them a solid choice for modified or performance-oriented engine builds where stock gaskets might not hold up.

The .040 inch thickness is a notable specification, often chosen to achieve a specific compression ratio or to help achieve proper piston-to-valve clearance in a hybrid setup. Cometic uses multiple layers of stainless steel, along with specialized sealing elements, to create a gasket that can conform to surface imperfections while maintaining a strong seal. This construction helps prevent leaks and ensures consistent performance, especially in engines that see more demanding use.
