What is the compressed thickness of this head gasket?

This Cometic MLS head gasket has a compressed operating thickness of 0.036 inches. This measurement is important for ensuring proper compression ratios after installation.

What makes this a Multi-Layer Steel (MLS) gasket?

An MLS gasket is constructed from multiple layers of stainless steel, which provides superior strength and resilience compared to single-layer gaskets. The outer layers are also coated with Viton for enhanced sealing performance.

Do I need to use any sealant with this head gasket?

No, Cometic's MLS head gaskets are designed to provide maximum sealing performance without the need for additional sealants. The Viton coating on the outer layers ensures a tight seal on its own.

About this part

Product Details

If you're rebuilding the top end of your 4A-GE engine, a reliable head gasket is crucial for sealing combustion pressure and coolant. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the demands of performance engines, ensuring a strong seal between your cylinder head and block.

Cometic's MLS design uses multiple stainless steel layers for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle high temperatures up to 482°F (250°C) and works well with different block and head materials, including aluminum to aluminum or aluminum to cast iron. This gasket has a compressed operating thickness of 0.036 inches and an 81mm bore, designed for the 20-valve 4A-GE engine. Because it's an MLS gasket, it doesn't require any additional sealants, making installation more straightforward.
