Valve V6 3.0 Special 8mm Stem 38.5mm 45 degree Exhaust Each
[30008EVOS]
$0.00

FITS ALL 12 VALVE V6 ENGINES

According to Jim K research 38.5 exhaust valves make better power than oversize valves. Several customers have been successful , so we have produced these 8mm standard diameter valves by popular demand.

  • The 1mm smaller stem and contoured back side allows better flow.
  • 16% lighter (13 grams) than the standard 9mm stem valves. This is worth power since the exhause seat pressure can be reduced.
  • These valves fit the stock seat
  • These 8mm stem valvesrequire SM1 Retainers & Keepers.

NOTE: We can special order any valve size you decide is best for your engine.
