What is the compressed thickness of this head gasket?

The compressed operating thickness for this Cometic MLS-5 head gasket is 0.066 inches. This measurement is important for maintaining proper compression ratios and valve-to-piston clearance.

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

No, Cometic 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.

Product Details

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

Cometic builds these gaskets with multiple layers of stainless steel for increased strength and resistance to corrosion.

With a compressed thickness of 0.066 inches and a 4.100-inch bore, these gaskets are designed to fit your LT1/LT4 engine precisely, and they don't require any additional sealants.

This gasket fits a range of GM vehicles from the mid-90s, including models like the Chevrolet Corvette, Camaro, and Pontiac Firebird. It's a well-built option for anyone looking to ensure a leak-free seal during their engine rebuild.
