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

Fits: Civic / CRX / Integra GSR B16A B18C VTEC / LS-VTEC / B20-VTEC**

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.

My puppy loves it
Color: Teething Stick
It's cute and a good size for my chihuahua puppy. It seems to be slightly tearing at the seam in the middle, but hopefully it will hold up.

LOVE this tough toy! My teething puppy is still enjoying it!
Color: Hedgehog
LOVE the hedgehog! Very tough! My dachshund has not been able to chew off any of the 'nubs', and does she try! lol The only thing is, the first thing she did was chew off the nose, but I discarded it and watched her closely to make sure she didn't chew off any more, and no, its still being chewed on. Wish I could find more toys like this one!!

still searching for a truly indestructible dog chew toy
Color: Hedgehog
My smallish dog (15 lb Boston terrier) got this chewed up within a half an hour. I didn't notice right away that he was also eating the parts he chewed off. Didn't last a day. Otherwise, quick shipping for a cute toy.

Good size for my pug!
Color: Dentachew 3 Pk
I love how it’s a good size for my pug it is easy for her to play around with. I had stuffed animals for her to play around with but it looked so silly to watch her play with something that is 10 times as big as her 😂. I had to buy her these toys and she seemed so happy when she first got them. It was so funny and interesting that she had to chew all three toys and decide which one she liked. At first she decided to play with the rope toy and she liked the rope toy, then she got curious with the rubber toys. She has decided that the rubber toys are her favorite and I’ve tried to engage with playing with her with the rope toy. She gets more interactive with the rubber toys! She also looked so relieved while chewing them so that’s a plus!
