  • As the hardness coating of a Titanium valve wears off, it works its own "pattern" into the valve seat.
  • The cooling process of a valve takes place when it is in contact with the seat.
  • The contact patch between the valve and valve seat becomes narrow and uneven.    
  • With diminishing contact area the valve loses its ability to cool and overheats.  
  • Valve becomes soft and deteriorates rapidly * Heat is what Destroys Valves, thats why its usually one Valve that loses clearance (Intake, left on Kaw-Suz, Intake right on Honda etc.)  
  • The Larger Intake Valves have more mass and don`t disapate the heat as fast as the smaller Exhaust Valves.

  • When you install "new" valves in your head, the hardness coating can deteriorate up to 40% faster as the new valve tries to adapt to the uneven surface left by the old valve. Each time you replace valves, the new set will not last as long as the previous set.  That's why valve change intervals DECREASE with each new set!!
  • Valve seats are cut to perfect alignment with valve guides. Wide, uniform contact patch is restored!!    

THIS IS A 3 ANGLE VALVE JOB!!! (30-45-60 degree)
