What is the compressed thickness of this head gasket?

This Cometic MLS head gasket has a compressed operating thickness of 0.030 inches. This specific thickness is important for maintaining proper compression ratios and valve-to-piston clearance.

What makes MLS head gaskets suitable for high-output engines?

MLS gaskets are made of multiple stainless steel layers, which increases their strength and ability to withstand high pressures and temperatures. The Viton coating on the outer layers also helps create a robust seal in demanding conditions.

Do I need to use any sealant with these head gaskets?

No, Cometic MLS head gaskets are designed to provide maximum sealing performance on their own and do not require any additional sealants. The embossed outer layers with Viton coating create a complete seal.

About this part

Product Details

This Cometic Multi-Layer Steel (MLS) head gasket is built with a compressed operating thickness of 0.030 inches and features a 4.040-inch bore, making it suitable for a range of GM LT1 and LT4 Gen-2 Small Block V8 engines from 1992 to 1996. These gaskets are constructed from multiple layers of stainless steel, with the outer layers embossed and coated on both sides with Viton, a heat-resistant rubber material rated up to 482°F (250°C). This advanced construction provides excellent sealing performance for high-output engines and can handle the stresses between aluminum heads and cast iron blocks, or between aluminum heads and aluminum blocks.

The multi-layer stainless steel design offers increased strength and resilience, allowing the gasket to rebound and resist corrosion. The Viton coating is engineered to perform in demanding sealing environments and on various surface finishes, ensuring a reliable seal without the need for additional sealants. The center shim layer is uncoated stainless steel and can be varied to achieve different thickness requirements, though this specific gasket is set at 0.030 inches compressed thickness. These gaskets are a solid option for rebuilding top ends on vehicles like the Chevrolet Corvette, Camaro, or Pontiac Firebird from the mid-90s.
