Manley 11660-10 Viper Race Master Exhaust Valve 2.055" +.100

Featuring a 2.055" head diameter and a +0.100" oversize stem length, these valves are engineered for high-performance engine rebuilds where additional stem length is required to restore proper installed height after seat and guide reconditioning.

Manley's Race Master valves are manufactured from high-strength one-piece stainless steel, providing excellent heat resistance, corrosion resistance, and durability under the extreme thermal and mechanical loads generated by high-output V10 powerplants. The precision-machined stem and head geometry ensure optimal valve-to-seat sealing and flow characteristics.

Key Features:

• Head Diameter: 2.055"
• Stem Length Oversize: +0.100" for corrected installed height
• Quantity: 10 valves per set
• Series: Race Master (R/M) — Manley's performance-grade valve line
• One-piece high-strength stainless steel construction
• Precision-machined for consistent sealing and flow
• Designed for Dodge Viper 8.0L V10 exhaust port application
• Suitable for performance engine rebuilds, racing, and high-output street applications

The +0.100" oversize stem length is a critical specification for engine builders who need to compensate for material removal during valve seat and guide reconditioning, ensuring proper spring installed height and valve train geometry are maintained. These are a direct upgrade or replacement-in-kind for Viper engine builds demanding reliability and performance.
