Cylinder Head Gasket (MLS) 81.50mm / 1.016mm SpeedFactory Honda B-series

MLS Head Gasket 81.50mm / 1.016mm SpeedFactory Honda

The SpeedFactory MLS Head Gasket 81.50mm / 1.016mm for Honda is engineered for high-performance engine builds where reliable sealing under extreme conditions is critical. Featuring an advanced 4-layer Multi Layer Steel (MLS) construction, this gasket delivers exceptional sealing performance for high-compression, turbocharged, supercharged and nitrous-assisted applications.

With an 81.50mm bore and a 1.016mm (.040") thickness, this gasket is suitable for engines with cylinder bores ranging from 81.00mm to 81.75mm. Embossed sealing rings around the combustion chambers improve sealing pressure and help prevent leaks under high cylinder pressure and head lift conditions.

An integrated silicone bead around the oil passages enhances fluid sealing, while the elastomer coating compensates for minor surface imperfections in the cylinder head and engine block. Enlarged head stud holes provide compatibility with 1/2" head studs commonly used in high-horsepower builds.
