Olds H/P 1.710in Exhaust Valve

The Olds H/P 1.710in Exhaust Valve by FERREA is a precision-engineered component designed for high-performance Oldsmobile engines requiring reliable exhaust flow management. This valve is essential for serious engine builders and mechanics working on vintage muscle cars and performance restorations where stock components no longer meet upgraded power targets. The 1.710-inch head diameter strikes an optimal balance between flow capacity and seat geometry, making it ideal for heads that have been ported or modified for increased displacement and RPM capability.

FERREA exhaust valves are manufactured to exacting tolerances using premium materials designed to withstand high-temperature and high-velocity exhaust gas exposure. The 1.710-inch diameter provides superior exhaust scavenging compared to OEM valves, allowing burnt gases to evacuate more efficiently and reducing residual heat in the combustion chamber. This improved scavenging directly translates to cleaner cylinder filling, better fuel mixture preparation, and increased power output across the RPM band.

Mechanics and engine builders upgrading Oldsmobile heads—particularly on 455 big-block and modified 400-series platforms—rely on FERREA exhaust valves for durability in street, strip, and competition applications. The valve's precision stem geometry ensures consistent sealing and minimizes carbon accumulation around the seat interface, extending service intervals and maintaining peak performance reliability. This makes it a trusted choice for those looking to enhance their vehicle's performance.
