What is the compressed thickness of this head gasket?

The compressed operating thickness for this Cometic MLS head gasket is 0.045 inches. This measurement is important for ensuring proper valve timing and compression ratios after installation.

What does the Viton coating on the outer layers do?

The Viton coating is a heat-resistant rubber material that enhances the gasket's sealing capabilities in harsh environments. It helps the gasket maintain a strong seal against various surface finishes and operating conditions.

About this part

Product Details

If you're rebuilding the top end of your 1988-1991 Honda Prelude SI, a solid head gasket is crucial for keeping everything sealed up tight. This Multi-Layer Steel (MLS) gasket from Cometic is designed to handle the demands of your engine, ensuring reliable performance.

Cometic builds these gaskets with multiple layers of stainless steel, which gives them strength and helps them resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes. This construction means you don't need to use any extra sealants; the gasket is ready to seal effectively right out of the box. It's suitable for use with both aluminum and cast iron blocks, and the center layer can be varied to achieve different thicknesses, like the 0.045 inch compressed thickness on this specific gasket for an 84mm bore.
