Product Description

The Cometic PRO2054T Top End Gasket Kit is engineered specifically for the Honda K20Z3 engine found in 2006-2011 Civic Si models, providing everything needed for a complete top end rebuild or cylinder head service. At the heart of this kit is the 0.030-inch thick Multi-Layer Steel cylinder head gasket with an 86mm bore, designed to handle the high compression ratios and cylinder pressures of the K20Z3's 11.0:1 compression and 8,000 RPM redline. The MLS construction features multiple layers of stainless steel with specialized coatings that allow micro-movement between layers while maintaining a perfect seal, making it ideal for both stock applications and modified engines running up to 250 horsepower.

Each gasket in the kit is manufactured using Cometic's advanced materials and precision processes to exceed OEM specifications. The reinforced gasket compounds utilize armor-clad, graphite, and galvanized steel construction specifically designed to seal irregular surfaces common on both stock and lightly machined cylinder heads. The non-stick properties of Cometic gaskets significantly reduce cleanup time during disassembly, as the material resists adhering to aluminum surfaces. This complete kit eliminates the need to source individual gaskets, ensuring proper fitment and compatibility across all sealing surfaces from the cylinder base to the valve cover, making it the preferred choice for enthusiasts performing K20Z3 engine rebuilds, head gasket replacements, or performance upgrades.
