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.

Aggressive chewer puppy approved

My aggressive chewer puppy loves this. It is pretty sturdy. He hasn't destroyed it yet and he's had it for over 3 months now.

Pretty hard to clean
Color: Cinamutt Roll - Large, Size: Large
We've had this for about a week now. I have 2 dogs, one small one about 55lb. I bought this for my big girl, but lil man is determined to get the best of this toy. Usually they don't both go after the same toys, so this is interesting. The trouble is, neither one of them can get all the treats out if something makes it all the way down into the crevice. It's surprisingly deep. The up side is that they'll try for quite a while before giving up. The down side is even if you put it in the top rack of the dishwasher, something stuck deep in there isn't going anywhere until you dig it out yourself. I tried a plastic knife but it broke the second time I used it in there. I wound up using the metal handle of a reusable straw cleaner. Which then I had to wash that, too. Then it needs to dry overnight before it can be used again. All in all, the dogs like it fine, it's gross to scrape out and wash, takes longer than most toys to dry, and I have the feeling that will eventually cause me to pass it to someone else's dog long before my two have gotten tired of it. At this point I'm pulling out of the toy rotation for a week or two because I'm not ready to clean it a third time.

Hyena Proof
Color: Acorn - Large, Size: Large
I have an American Bulldog that would chew a brick if he didn’t have an alternative lying around. They won’t last forever (nothing does) but we’ve had two of these over the course of a year and for him that is nothing short of a miracle. And that is daily chewing like it’s his job. I highly recommend the Acornucopia for aggressive chewers with jaws like hyenas…so it’s probably great for your dog too.
