• No compromise design
• High-flow design includes a 50  seat angle, no dish valve face and 5 mm stem diameter (intake and exhaust) for better flow, higher compression and higher rpm
• Exhaust valve has a 5 mm stem and is not compatible with stock retainer and lock. Will need to use retainer PART #0926-2036 and lock PART #0926-1820. Valve guide will also need to be machined to accept larger stem size.
