SpeedFactory High Performance MLSS-HP Head Gaskets for Honda/Acura B-Series VTEC Engines, Including LS-VTEC & B20-VTEC

PAIR WITH OUR SPEEDFACTORY RACING 4140 HEAD STUD KIT FOR THE ULTIMATE SEALING COMBO - CLICK HERE!

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. 

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 0.040” thickness makes up for cylinder head and block surfacing vs the OEM 0.028” thickness and we've also incorporated 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.
