What is the compressed thickness of this head gasket?

When properly installed and compressed, this Cometic head gasket has an operating thickness of .080 inches. This measurement is important for maintaining the correct compression ratio for your engine.

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

No, Cometic's MLS head gaskets are designed to provide a maximum seal without the need for additional sealants. The Viton coating on the outer layers ensures a tight seal against the engine block and cylinder head surfaces.

What is the advantage of Multi-Layer Steel (MLS) construction?

MLS construction provides increased strength and durability compared to single-layer gaskets. The multiple stainless steel layers help the gasket rebound and resist corrosion, ensuring a long-lasting seal under high-output engine conditions.

About this part

Product Details

If you're rebuilding the top end of your 1992-1996 GM LT1 or LT4 small block V8, a solid set of head gaskets is crucial for a leak-free seal. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the demands of these engines, offering a reliable barrier between your cylinder head and engine block.

Cometic uses multiple layers of stainless steel for increased strength and corrosion resistance, which also allows the gasket to rebound and maintain a tight seal. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes, making it suitable for both aluminum and cast iron blocks. This particular gasket has a 4.040 inch bore and an operating thickness of .080 inches when compressed, with valve pockets designed to accommodate the LT1/LT4 engine's valve train.

This gasket fits a range of GM vehicles from the mid-90s, including the Chevrolet Camaro, Corvette, and Pontiac Firebird. It's designed for a direct fit, meaning no sealants are required for installation, simplifying the rebuild process.
