Stage 1 CNC Ported Cylinder Heads

 

These are CNC Ported in house using the latest in simultaneous 5 axis Cad/Cam technology. We have over 30 years of cylinder head manufacturing and porting experience. We have worked with many of the top teams in NASCAR, NHRA and INDYCAR.

 

  • Send us your complete cylinder heads and we will perform the following and reassemble with your valves.
  • Cylinder heads are cleaned and disassembled.
  • Cylinder heads are hardness checked.
  • Cylinder heads are pressure checked to 60 psi.
  • Simultaneous 5 axis CNC porting of the intake and exhaust valve bowls, also includes radius of the intake inlet.
  • Precision 5 angle valve job. We maintain the factory measurement spec from the deck to the valve.
  • Flow increases of 35 CFM on both intake and exhaust ports.
  • Cylinder heads are presure checked at 60 psi once again after porting.
  • Face and backcut intake valves.
  • Face exhaust valves.
  • 32 new spring cup bases.
  • 32 Chrome Moly retainers, specifically made for SoCal Diesel.
  • 32 new Beehive "Ovate" wire valve springs. We designed these springs specifically for the performance needs of a Duramax. They are made specifically for SoCal Diesel and are not available from anyone else.
  • 32 new Valve stem seals.

Prior to assembly the cylinder head deck, intake and exhaust surfaces are given a clean up cut to insure flatness.
