RIVA High-Performance Valves are engineered to improve reliability and performance in high-boost supercharged & turbocharged engines. Intake valves are built from high-grade EV-8 (24-4N) stainless that is extremely resistant to corrosion. Exhaust valves are built from Inconel alloy (IN-751) that is highly resistant to heat damage. Valve heads have been redesigned for increased airflow and durability. Valve stems feature hard-chrome plating for superior wear & lubricity. Kits include high strength valve locks, precision machined from 4130 chromoly.

Drop-In Valve Kits: Direct drop-in replacement valves require no machining of the cylinder head. Oversized Valve Kits: +1mm Intake & +1mm Exhaust valves deliver more airflow (requires machining of cylinder head)..
