Cometic Honda Prelude 87mm 97-UP .060 inch MLS-5 H22-A4 Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with an 87mm bore and a compressed operating thickness of 0.060 inches, specifically for the 1997-2001 Honda Prelude. It's constructed from multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes, making it suitable for both aluminum and cast iron blocks. This design means the gasket seals effectively without needing any additional sealants.

The multi-layer stainless steel construction allows the gasket to rebound and resist shearing forces, especially important when mating different block materials like aluminum heads to cast iron blocks. The center layer is stainless steel and can be varied to achieve different thicknesses, like the 0.060 inch spec on this particular gasket. This updated design helps ensure a solid seal for high-output engines.
