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

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.

Easy and convenient way to block off space!
Color: Brown, Size: 4 Panel, Color: Brown, Size: 4 Panel
Turned part of my basement into a dressing room. Ordered several of these and they worked out perfectly. I was able to separate the “guest room” area as well as our gym! Kept my space neat and private. And no assembly!

Great visual barrier for home office
Color: Brown, Size: 4 Panel
This is going to work perfectly for me to create a visual barrier in my home office. No assembly required. Literally took it out of the box and stood it up on carpet. No concern that it will randomly fall over. Would buy again.

Good product. Wrong color!!
Color: Brown, Size: 6 Panel
The product is great but it's not as advertised. It's supposed to have bamboo-colored panels. The color of light bamboo. It has dark panels. Mahogany colored panels. Way too dark!!! Looks nothing like the picture on the website. Made a dark space even darker.
