Description
For individuals with high horsepower and high EGT setups who want a valve that can withstand temperatures of up to 2000°F, GSC Power-Division Super Alloy Exhaust Valves are available for the B58 and S58 Engines. When combined with the GSC Manganese bronze valve guides, the smooth, long-lasting finish of the chrome-plated stems of the Super Alloy exhaust valves provides increased longevity and improved lubrication. Each valve is designed with strength, heat resistance, and performance in mind. To save weight, the under-head dish is optimized, and the backcut and swirl polished heads improve airflow without compromising durability.
