Manley 12631-1 Race Master Exhaust Valve Ford GT350 Voodoo 5.2L

The Manley 12631-1 Race Master Exhaust Valve is a single-piece, high-performance engine valve engineered specifically for the Ford GT350 Voodoo 5.2L engine. Designed to meet the rigorous demands of bracket, drag, and oval track racing, the Race Master series represents Manley's trusted solution for high-output engines operating at speeds up to 8,000 RPM.

Key Features:

• XH-426 Stainless Steel Construction — Exhaust valves are manufactured from Manley's exclusive XH-426 stainless steel alloy, delivering superior heat resistance and long-term durability under extreme conditions
• Chrome-Coated Stems — Stems feature a hard chrome coating approximately 0.0002" thick — far more substantial than the flash chrome used by competitors — providing exceptional wear resistance and surface hardness
• Hardened Valve Tips — Superior hardened tips resist cracking and erosion, unlike puddle-applied stellite tips found on competing valves
• Swirl Polished Under-Head Area — The under-head geometry is swirl polished to optimize airflow and reduce turbulence entering and exiting the combustion chamber
• Fully Machined Combustion Face — Precision-machined combustion face ensures consistent seating and maximum sealing performance
• Race-Proven Design — Trusted by bracket racers, drag racers, and oval track competitors running below 8,000 RPM

Manley Performance has been at the forefront of performance valve design since the late 1960s. The Race Master series uses exclusive materials not available from other manufacturers, making these valves among the strongest and most durable in their class. Sold individually (quantity: 1).
