GSC P-D Chrome Polished Exhaust Valve - 30.5mm Head (STD) - Evo 1-9 / 90-98 DSM (Set 8) Vehicle Model_Genesis Accurate air/fuel ratio measurementPart #: 2001 8 When designing these valves, GSC used advanced 3D design and simulation programs to create a stronger and higher flowing valve head design. Prototypes were used in the specific applications to make sure that they have the highest flowing valve head that is available on the market today. The materials they have used have less valve distortion at the face than any of the tested designs which allow for better sealing under extreme
