What does the .030 inch oversize mean for this head gasket?

The .030 inch oversize indicates that this gasket is slightly larger than the standard bore size. This is typically used when the engine block or cylinder head has been machined, or when using pistons that are also oversize, to ensure a proper seal.

What is the advantage of a Multi-Layer Steel (MLS) head gasket?

MLS head gaskets are constructed from multiple layers of steel, which allows them to better handle higher cylinder pressures and temperatures. They also offer improved rebound characteristics and resist corrosion, contributing to a more reliable seal.

Does this head gasket come with any other parts needed for installation?

This product is for the Cometic MLS head gasket only. It is recommended to consult the vehicle's service manual or Cometic's installation guidelines for any additional components or hardware that may be required for proper installation.
