Description

Details

Race-proven durability!

Our MAP valves feature black oxide nitrating (a superior hardening process) which penetrates into the ultra-EV8 stainless steel core material, forming a super-hard outer layer. This "Black Diamond" finish adds surface hardness as well as a smoother exterior coating which greatly reduces friction. This reduction in friction allows for tighter tolerances (fit) and provides long-lasting durability.

  • These valves are vastly superior to factory valves and other so-called "performance" finishes such as hard chrome.
  • Our induction welded, heat-treated tip prevents mushrooming and eliminates the need for lash caps.

Oversized Valves Are Available From MAP Cycles, Inc.

  • 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.

NOTE: Always be sure to check piston clearance before installing oversize valves.
