Ferrea Pontiac BB (KRE Head) 1.7in 11/32in 6.2in 24 Deg S-Flo Dish Head Comp Plus Exh Valve-Set of 8

If you're rebuilding the top end of your Pontiac big block, especially one fitted with KRE heads, you'll want to pay close attention to your exhaust valves. These Ferrea Comp Plus exhaust valves are designed to handle the demands of a performance engine. They feature a 1.7-inch diameter head and a 6.2-inch overall length, with a 24-degree sealing angle, all built around an 11/32-inch stem.

Ferrea uses a high-strength steel alloy for these valves, heat-treated to ensure they can withstand the high temperatures and pressures found in performance Pontiac engines. The S-Flo dish design helps improve airflow over the valve head, contributing to better cylinder filling and exhaust scavenging. This set includes eight valves, enough for a complete V8 engine, and they're well-made to be a reliable part of your engine build.
