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

These MLS gaskets have been purpose built to provide an excellent seal on high compression/nitrous/turbocharged engines and when used in combination with our Extreme Duty L19 Head Stud Kit have been real world tested to 1000hp with excellent results (and to 1400hp+ with stainless wire O-ringed sleeved blocks). Note that this is not a stopper ring type design.

We have found over years of trying many different 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.

The 0.040” thickness makes up for cylinder head and block surfacing vs the OEM 0.028” thickness and 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. Our design also utilizes a unique internal silicone bead on the oiling passages for improved sealing.

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.
