Power-Division Super Alloy Exhaust Valves for the B58 and S58 Engines
are for those running high horsepower, high EGT set ups that need a
valve that will last in 2000°F conditions. The Super Alloy Exhaust
valves have chrome polished stems to create a smooth, durable finish for
added life and better lubricity, especially when paired with the GSC
Manganese bronze valve guides. Strength, heat resistance, and
performance are engineered into every valve. Under head dish is
maximized for weight savings while swirl polished and backcut heads
promote better air flow without sacrificing durability.
