GSC
32mm in size
Swirl polished heads for smoother air flow over the valve
Back cut to reduce valve weight for higher rpm, higher boost pressure, and allow for more aggressive cam profiles without increasing valve spring seat pressures
Valve stems are micro-polished to allow for less oil retention on the stem which creates less drag on the stem to guide for a smoother motion
Fully nitrated ( this includes the 45 which increases valve life and makes a better seal at the valve seat for improved cylinder pressure) also reduces carbon buildup on the backside of the valve
Intake valves are a modified 21-4n stainless and Exhausts are a modified 23-8n stainless material for high heat capacity while maintaining longevity
Valve tips are either hardened or have a stellite wafer tip fused so that the tip is within 5 Rockwell C of the rocker or valve tappet for extended life and less wear
Valve tip lengths. They have taken extra time to adjust tip heights on the applications to require less tipping of the valve to maintain proper tip height for proper valvetrain geometry and to cut down on install times when setting valve lash
They have also adjusted the Keeper grove to properly balance intake and exhaust spring pressures to reduce the use of valve spring shims and maximize performance from their spring and retainer kits
Valves will work with an OEM keeper/lock or when available their upgraded keeper/lock. It's not mandatory but it is suggested that any valve lock not be reused on performance applications due to material grooving
Includes (8) exhaust valves
