1990-2001 Acura Integra, 1999-2000 Honda Civic Si, and 1997-2000 Honda Civic Type-R High-Performance MLSS-HP Head Gaskets by SpeedFactory

SpeedFactory Racing is proud to release our line of high-performance Honda/Acura B-Series VTEC MLS head gaskets!

These MLS gaskets have been purpose-built to provide an excellent seal on ALL B-Series VTEC applications, from factory setups to high compression/nitrous / turbocharged / supercharged engines.

Our gasket utilizes a 4-layer design with specialized embossments that increase active combustion sealing height, ideal for high-output engines that experience high levels of head lift/movement. The thickness is ideal for use with O-rings in extremely high-output applications that require it for reliable combustion sealing. We’ve also incorporated a unique internal silicone bead on the oiling passages for improved sealing.

When used in combination with our Extreme Duty L19 Head Stud Kit, our gaskets have been real-world tested to 1000HP with excellent results in non-O-ringed blocks (and up to 1400hp+ when used with O-ringed sleeved blocks). Note that this is NOT a stopper ring-type design.

We have found over years of trying many different B-Series MLS gasket designs that once you reach an output level that eclipses what a non-stopper ring MLS gasket will reliably hold, adding a stopper ring only provides limited improvement and O-ringing the cylinder head or block becomes a necessity for a reliable combustion seal. The stopper ring becomes more of a hindrance to O-ring placement and function at that point and we have had much better success running O-rings with a non-stopper design.

Another unique feature is enlarged head stud holes for compatibility with 1/2” head studs (the 2 locating dowel holes remain OEM sized and are the only holes that need to be modified if running 1/2″ head studs, greatly reducing the time & effort required during engine assembly). We have been reliably running these gaskets on wet deck Bullet Billet blocks which utilize 1/2″ head studs at 1400+whp.
