What is the compressed thickness of this head gasket?

This Cometic MLS head gasket has a compressed operating thickness of 0.030 inches. This dimension is critical for maintaining proper compression ratios and valve timing after installation.

What is Viton and why is it used on this gasket?

Viton is a heat-resistant synthetic rubber material that can withstand high temperatures, up to 482°F (250°C). It's used on the outer layers of this gasket to ensure a reliable seal in demanding engine conditions.

Does this gasket require any sealant?

No, Cometic MLS head gaskets are designed to provide maximum sealing performance without the need for additional sealants. The embossed layers and Viton coating create a robust seal on their own.

About this part

Product Details

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example for your 1985-1991 Toyota Corolla with a 4A-GE engine. If you're rebuilding the top end of your 4A-GE, this gasket is designed to handle the demands of high-output engines and ensure a solid seal between your cylinder head and block.

This gasket is constructed with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This advanced coating helps it seal effectively against aluminum heads and blocks, or aluminum heads and cast iron blocks, even with the shearing forces that can occur between different metals. The center layer is stainless steel and can be varied in thickness, with this specific gasket set to a compressed operating thickness of 0.030 inches and an 81mm bore, making it a direct fit for your 16-valve 4A-GE engine.
