Production begins with a one-piece forging, where the head is formed under a slow two-step process to maintain optimal material grain flow. Each valve undergoes multiple CNC machining steps, stress-relieving heat treatments, and either nitride hardening or application-specific coatings. Final grinding and our patented Superfinishing process ...\u003c\/p\u003e\n\u003cp\u003eWith over 30 years of racing valve development, Supertech combines this deep experience with state-of-the-art manufacturing and testing technology including ultrasonic inspection, x-rays, laser measurement, and Finite Element Analysis (FEA). In collaboration with top engine builders, we conduct continuous testing to refine every valve for high flow, extreme durability, and world-class performance.\u003c\/p\u003e\n\u003cp\u003eThis valve features a Single Groove lock groove, a Dished face profile, and measures Oversize +1mm in diameter, with an overall length of 98.10mm.
