SpeedFactory Racing High Performance MLSS-HP Head Gaskets for Honda/Acura B-Series VTEC Engines

SpeedFactory High Performance MLSS-HP Head Gaskets for Honda/Acura B-Series VTEC Engines, Including LS-VTEC & B20-VTEC 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. **B20-Vtec requires 84mm or Larger Head Gasket FITMENT:Honda/Acura B16A B18C VTEC enginesLS-VTEC & B20-VTEC **Must Use VTEC Conversion Stepped Dowel Pins Available Sizes: 81.50mm (Use for 81.00-81.75mm/3.218” maximum bore) 82.00mm (Use for 82.00-82.25mm/3.238” maximum bore) 83.00mm (Use for 83.00-83.25mm/3.277” maximum bore) 84.00mm (Use for 84.00-84.25mm/3.316” maximum bore) 84.50mm (Use for 84.50-84.75mm/3.336” maximum bore) 85.00mm (Use for 85.00-85.25mm/3.356” maximum bore) 0.040”/1.016mm thickness FEATURES: MLSS-HP (Multiple Layer Stainless Steel + Silicone Bead) Head Gasket optimized for high performance use 4-layer MLS design with specialized embossment increases active combustion sealing height, ideal for forced induction engines that experience high levels of head lift/movement.
