Supertech Performance NEVI-1007-VE-8 Inconel Exhaust Valves SR20VE +2mm Oversize

These valves feature a +2mm oversize head diameter for improved airflow and performance in ported cylinder heads.

Specifications:

• Head Diameter: 31.15mm (+2mm oversize)
• Stem Diameter: 5.97mm
• Overall Length: 100.50mm
• Material: Inconel nickel-based alloy

Key Features:

• One-piece forged construction with slow two-step forging process for optimal material grain flow
• CNC machined in multiple steps for precise dimensional accuracy
• Heat treatment for stress relieving followed by nitride hardening treatment
• Patented Superfinishing process eliminates surface imperfections
• Inconel material provides superior heat resistance for turbocharged and high-temperature applications
• Oversize valve heads increase airflow potential when matched with proper valve seat machining

Inconel nickel-based alloy material is engineered for exhaust valves in engines that reach extremely high exhaust gas temperatures. This material offers exceptional temperature distribution and heat resistance, making it ideal for turbocharged, supercharged, and high-performance naturally aspirated engines. Supertech applies over 30 years of racing experience combined with state-of-the-art equipment including ultrasonic testing, x-rays, laser measurement, and computerized finite element analysis to ensure every valve meets the highest quality standards.

Note: Oversize valves require cylinder head machining or aftermarket valve seats for proper installation. Professional installation and verification of piston-to-valve clearance is required.
