• Our oversized valves (OS) are flow tested for maximum performance.
• Oversized valves can also be used to rejuvenate sunken valve seats while correcting valve geometry.
• The OS valve features relocated keeper locations to accommodate hi-lift racing cams and springs. This saves additional machining expense.
