The Cometic Gaskets Honda K20A2/K20A3/K20Z1/K24A1 .030in cylinder head gasket is purpose-built for K-Series engine builders and mechanics seeking reliable OEM-level or performance-enhanced sealing. Whether you're rebuilding a stock K-engine, upgrading to a higher compression ratio, or assembling a tuned variant, this 88.0 mm bore gasket delivers the critical seal between cylinder head and block that prevents combustion blow-by and coolant leakage. Designed to handle the demands of both naturally aspirated and lightly boosted K-platforms, this gasket is an essential component for any serious Honda engine work.
This gasket features Cometic's proven multi-layer steel (MLS) construction, which provides superior conformability and sealing integrity compared to traditional composite gaskets. The 0.030 inch compression thickness is engineered to maintain proper combustion chamber volume and compression ratio, critical when working with performance builds or modified heads. Multi-layer steel technology resists heat cycling, prevents gasket creep, and tolerates both stock and ported head surfaces far better than single-layer alternatives—making it the preferred choice for shop-quality rebuilds where reliability and longevity matter most.
Mechanics and engine builders working on K20A2, K20A3, K20Z1, and K24A1 platforms—whether in Civic Si, RSX, Accord, or swapped applications—will find this gasket essential for any head removal or full engine build. The 0.030 inch thickness is sized for standard-to-mild overbore scenarios and complements both stock and aftermarket valve train upgrades. Proper installation requires clean, flat mating surfaces and correct head bolt torque sequencing; this gasket performs best when paired with quality fasteners and professional assembly techniques. For shops and enthusiasts demanding proven sealing performance on Honda's most popular performance engine platform, Cometic's MLS design offers the durability and consistency expected from a top-tier gasket manufacturer.
