Ferrea Honda B18A1/B1/B20A 29mm 6.54mm 106.02mm 30 Deg Flo Dish Hd +1mm Comp Plus Exh Valve-Set of 8

This set includes eight Ferrea Comp Plus exhaust valves, each measuring 29mm in diameter with a 6.54mm stem and a 106.02mm overall length. These valves are designed with a 30-degree flo-dish head and are 1mm oversize compared to stock, intended for Honda B18A1, B1, and B20A engines. They are a well-built component for rebuilding or upgrading your engine's cylinder head.

Ferrea's Comp Plus valves are constructed from high-quality stainless steel, chosen for its ability to withstand the high temperatures and stresses found in performance engine applications. The 1mm oversize head helps to improve airflow into the combustion chamber, potentially leading to better performance. The robust construction ensures they can handle the demands of an engine that's been tuned for more power. When installing these, ensure your valve guides and seats are in good condition to match the new valve dimensions.
