- Increased Flow
The Edelbrock #9753 Exhaust Valves are designed for high-performance Pontiac engines, including the 389 (6.4L) and 455 (7.5L) models. Crafted from durable stainless steel, these 1-piece valves feature swirl-polished, hardened tips for enhanced durability and performance. The undercut stems are engineered to improve airflow, contributing to increased engine efficiency and power output. With an overall length of approximately 5.23 inches and a +0.120-inch longer design than stock, these valves are suitable for performance applications that demand improved flow characteristics. They are compatible with Edelbrock #60599 cylinder heads and come as a set of eight, making them ideal for comprehensive valve upgrades in Pontiac V8 engines. The hardened valve stems are 11/32 inches in diameter, ensuring resistance against wear and heat stress during high-performance operation. These exhaust valves are a vital component for enthusiasts seeking to optimize engine breathing and overall power delivery, especially in racing or high-performance street applications. Please note, these valves are Prop 65 compliant and are intended for automotive use, not emissions certification. Installation should be performed by qualified technicians familiar with engine modifications to guarantee optimal performance and durability.
