RWA1495 1.89" 2.3 Intake Valve is .100" longer than a stock valve and is designed to work with high lift small base circle camshafts. These valves have excellent flow characteristics —especially at lower lift— and lighter overall weight for higher RPM capabilities make these an superb choice for high performance engines. Attributes include chrome stems, stellite tips and swirl polishing. They're great for improving the flow of stock heads.
