What makes this head gasket so special?!
 
Their design is more rigid compared to the O.E "770" The Black PTFE coating is able to withstand and transfer heat better.
 
The main thing with these is that they are embossed around all the sealing areas so the gasket performs like a crush washer.
 
 
About Six-Star® Head Gaskets
The SIX STAR MLS "STOPPER" HEAD GASKET is ideal for both aluminum heads and aluminum blocks. A better alternative compared to other gaskets made of bonded materials that fail prematurely due to load and heat dissipation problems!
By design, the MLS (multi layer steel) STOPPER head gasket has a folded bore bead that encompasses the entire combustion area. This allows for a concentrated seal along a pin-pointed surface area encompassing the combustion chamber. The gasket promotes an even torque load across a wider area and requires less clamp force resulting in less bore distortion conforming load across the sealing area! No re-torque necessary.
Gaskets are made of Stainless Steel and the outer layers of the gasket are embossed and coated on both sides with a fluoroelastomer rubber based material Viton.
 
We have used these gaskets on all of our engine rebuilds for over 10 years without any reported failures.
 
These upgraded Subaru Head Gaskets fit all Turbo and Non Turbo 2.5's. Subaru WRX, STI, Legacy, Outback, Forester, Baja and Impreza engines both Single and Dual Overhead Cam.
