Cometic MLS head gaskets are constructed from multiple layers of stainless steel for strength and contain load-controlled embossments that conform load distribution across the sealing area. This creates an exceptional seal by requiring less clamp load--resulting in less bore distortion. The stainless steel outer layers utilizing FKM (Viton®) rubber coating, a high-temperature and chemical-resistant polymer. A topcoat of PTFE aids in resistance to fret and increased cold sealing. MLS head gaskets are available for most aftermarket cylinder heads; as with all of Cometic's MLS head gaskets, no sealants or re-torque is required.

Q:

Are these manufactured with steam holes? If not, can they be drilled without compromising the gasket?

Asked by ERIC on March 17, 2018

I have drilled them with no problems, steam holes on the intake side, are not needed, only drill the holes on the exhaust sides...

The description of these head gaskets state they are for a 4.155" bore but it claims to be for a cylinder bored 0.040 over. That would make it 4.165" so which is it?

Asked by JOSEPH on July 10, 2017

A:

it is .030" over but the compression thickness is .040"
