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.

    My Husband’s Favorite Socks
    Size: Large, Color: (035) Steel / White / Black
    The Under Armour Unisex Training Cotton No Show Socks have become my husband’s absolute favorite socks—and he’s pretty picky about socks. Comfortable Fit: They’re soft, comfortable, and fit well without being too tight. They stay in place all day with no slipping or bunching. Great for Everyday Wear: Perfect for workouts, walking, and everyday use. They provide just the right amount of cushioning without feeling bulky. Durable & Long-Lasting: These hold up really well through regular wear and washing. They keep their shape and don’t wear thin quickly. Reliable Under Armour Quality: You can tell they’re well made. Consistent quality that matches what you expect from Under Armour. Overall Impression: When someone has a favorite sock and keeps reaching for it, that says everything. These are comfortable, durable, and dependable.

    Excellent athletic socks
    Size: Large, Color: (100) White / White / Black
    Solid athletic socks at a great price. Not too thick, not too thin. Second time I've purchased them. They last longer than most socks I've used in the past too. Only concern is the sizing. I may be reading the sizing chart wrong, but for my size 13 feet it says XL are the correct sock size. I've ordered Large twice and they're perfect. I would imagine the size Large socks would also fit up to size 14 shoe, but probably need to go with XL if foot is lager than 14.
