Pontiac C/P 1.900 Exhaust Valves

The Pontiac C/P 1.900 Exhaust Valves represent a precision-engineered component set purpose-built for high-performance Pontiac V8 engines. This complete set of eight stainless steel exhaust valves is manufactured to Competition Plus specifications, delivering the durability and dimensional accuracy required for serious engine builders and performance technicians working on Pontiac powerplants. The 1.900-inch head diameter and 11/32-inch valve stem are optimized for efficient exhaust scavenging in high-RPM applications.

Each valve measures 6.450 inches in length and is constructed from stainless steel, a material selection that provides superior corrosion resistance and thermal stability compared to standard cast iron valves. The stainless composition maintains structural integrity under sustained high-temperature exhaust cycling, a critical requirement in competition or heavily modified engines where stock components fall short. The Competition Plus designation indicates these valves meet tighter tolerances than OEM replacements, ensuring consistent sealing and flow characteristics across all eight cylinders.

This valve set serves engine builders, machine shops, and Pontiac V8 enthusiasts upgrading or rebuilding classic performance engines. Whether for a complete engine overhaul, restoration of vintage muscle cars, or performance modifications, these precision components provide the reliability and dimensional consistency necessary for professional-grade work. The set includes all eight exhaust valves required for a complete V8 cylinder head, eliminating the need for individual valve sourcing.

Pontiac V8 engines remain popular in restoration and performance communities, and quality OEM-specification or upgrade components ensure reliable operation and proper engine management. These Competition Plus stainless valves bridge the gap between stock replacement and full racing specifications, making them suitable for both street-driven restorations and higher-demand applications.
