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 is 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
