*Note1: All Cylinder Head Porting is custom tailored to the individual customer need.   

*Note2: From our experience, even brand new OEM valves have too much run-out for our liking.  We recommend using our Stainless Steel swirl polished performance valves which are OEM sized in place of the OEM valves for extra peace of mind.

  1. Stainless Steel Swirl Polished Intake/Exhaust Valves - $399.00US
  2. Inconel Exhaust Valves (recommended for Turbo applications) - $1198.06US
  3. Titanium Intake Valves (recommended for high rpm applications) - $1633.72US
  4. Manganese/Bronze Valve Guides (recommended for Turbo applications) - $364.52US
