Pontiac H/P 1.660in Exhaust Valves

The FERREA Pontiac H/P 1.660in Exhaust Valves (set of 8) are precision-engineered stainless steel components designed for Pontiac V8 engine builds demanding high-performance durability and reliability. Part number F5064-8, this exhaust valve set delivers the flow characteristics and thermal stability required in performance and racing applications where OEM valve quality cannot meet modern demands.

These valves feature a 1.660-inch head diameter paired with an 11/32-inch valve stem and 5.230-inch overall length, specifications that ensure proper seating in Pontiac V8 cylinder heads while maintaining correct flow dynamics. The FERREA 5000 Series stainless construction provides superior corrosion resistance and higher temperature tolerance compared to standard iron valves, critical factors in engines operating at elevated RPMs or in high-heat environments. The set includes eight valves—one complete exhaust valve kit for a full V8 engine, eliminating the need for separate purchases.

This product is intended for engine builders, performance shops, and Pontiac V8 enthusiasts restoring or upgrading classic and muscle cars. Whether rebuilding a carburetor-fed 400, 455, or modified V8, these exhaust valves support higher valve lift and extended valve events common in cam upgrades and performance modifications. FERREA's reputation in the aftermarket engine component industry stems from precision manufacturing and material selection that prioritizes longevity in demanding conditions—making this valve set a dependable choice for serious engine work.
