Supertech Toyota 3SG 87mm Bore 0.055in (1.40mm) Thick MLS Head Gasket

Supertech is known for making solid valvetrain components, and this Multi-Layer Steel (MLS) head gasket is built to the same standards for your Toyota 3SG engine. If you're rebuilding the top end of your 3SG, a new head gasket is a critical part of ensuring a good seal between the cylinder head and the engine block. This gasket is designed with an 87mm bore, matching the standard bore size for many 3SG applications, and it's 0.055 inches (1.40mm) thick, which is a common thickness for stock replacement or mild performance builds.

MLS head gaskets are a popular choice because they offer improved sealing capabilities over older composite designs, especially under higher cylinder pressures. The multiple layers of steel, often with specialized coatings, allow the gasket to conform to the mating surfaces while resisting blowout. This particular gasket is a direct fit for engines requiring an 87mm bore and 1.40mm thickness, making it a straightforward replacement during an engine overhaul.
