Some Cometic gaskets are made to order and do have a longer lead time than standard sizes. Lead times on these custom sizes are closer to 2-4 weeks, so please call before ordering for anything that may not be considered a standard size
Cometic Head Gaskets feature a unique Multi-Layer System (MLS) that has special high-temp materials that meet the demands of a variety of harsh sealing environments, load conditions and surface finishes.
Cometic Gasket has developed some of the highest performing gaskets available on the market that are proven under the most demanding track conditions. Cometic head gaskets are constructed from multiple layers of stainless steel for strength and excellent rebound characteristics. The outer layers are coated to create a superior corrosive-resistant seal that can withstand extreme cylinder pressures.
