Cometic cylinder head gaskets are carefully engineered to provide consistent sealing under the most demanding high horsepower applications.

What is MLS?

MLS stands for Multi-Layer Steel. MLS head gaskets are comprised of three or five layers of stainless spring steel. The outer layers are an embossed Viton coated stainless steel providing a superior seal with excellent rebound characteristics and are corrosive resistant. MLS head gaskets reduce bore distortion and withstand extreme cylinder pressures. The MLS design is also used in a superior line of exhaust manifold/header gaskets.

Can MLS head gaskets be used with motors setup with o-rings or receiver grooves around the cylinder bores?

No. MLS head gaskets require smooth, flat and true head and deck surfaces to seal. Most of the time with o-ring setups the wire and groove fall where our gasket’s combustion seal is located; therefore, the wire will hold the gasket and not allow proper compression while the receiver grooves allow combustion gases to escape.

What surface finish is required to us an MLS head gasket?

A surface finish of 50 RA (roughness average) or finer, is recommended for a proper gasket seal. Anything rougher may conflict with the gasket design.

What head bolt/stud torque do you recommend when using an MLS gasket?

When using MLS head gaskets always refer to the manufacturer of the fastener to determine accurate torque values. Appropriate torque is critical when installing new gaskets of any kind.

Why does Cometic recommend MLS gaskets to be installed dry?

Cometic Multi-Layer Steel (MLS) head gaskets go on dry because they are coated with a sealant. Each MLS head gasket is coated with a .001" thick Viton rubber that is bonded to the outer stainless steel layers. Adding an additional sealer can hinder the performance of an MLS head gasket.

Can I order head gaskets with a different thickness and/or bore size than you have in your catalog?

Yes. Call Orient Express with the engine type or Cometic standard part number (search online or in our catalog) along with the bore size and thickness you would prefer and we will create your custom gasket. (800.645.6521)
