Cometic Head Gasket - 1ZZ BIG BORE 82.0-82.5MM - 0.027" Thick (C4497-027)

Description

Super tough Cometic multi-layer steel head gasket specifically for big bore 1ZZ-FE engines. If you’ve sleeved your 1ZZ-FE and have bored it to 82.0 or 82.5mm this is the gasket you need. Thickness is 0.027″ which is just slightly thicker than stock and has no major impact on compression ratio. Works great NA or with a turbo or nitrous.

Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.027". Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.
