BMW m20 High Performance Exhaust Valve, High quality stainless racing valve featuring hard chrome coated stem, hardened steel tip, 45* seat with 30* back cut.
The exhaust valve is not the restrictive part of the m20 head so fitting large over size is not generally required, however better arrangement of seat angles can be very beneficial! These exhaust valves are 1mm oversize to allow for cutting fresh multiple seat angles without compromising installed height. Also leaving room for very large intake valve without running into valve clash at high cam overlap.
Our stainless steel intake valves are manufactured from an enhanced version of EV8 (21-4N) steel. We have chosen this material specifically because it’s the highest grade of steel available and provides the strength to withstand just about any application. Our exhaust valves are made from EV16 (21-8N) or EV8-Nb/w for even greater strength at higher temperatures. Our stainless steel valves are one piece forged valves, and depending on the application feature hardened tips, hardened seats, swirl polish, undercut, and our black nitride coating. Our black nitride coated valves feature a harder surface area and a smoother finish, providing less friction and subsequently longer life.
Manufactures a variety of high performance Inconel valves for many applications. These valves are manufactured from a Nickel base super alloy material (Inconel 751 or Nimonic 80A) this material is chosen because it is designed to withstand very high temperatures. These valves feature a one-piece forging, hardened tip, and our “superfinish” stem. Our Inconel valves are extremely popular choice for turbo and supercharged applications.
