The long awaited SpeedCircuit Heads for the 4B11 Evo X are now available! All SpeedCircuit heads are completely stripped down and rebuilt, including new parts where necessary. There are 3 stages of heads available.

Stage 1 includes:

• Valve job
  
• Bowl work to blend the stock machine cuts into a larger bowl
  
• Resurface (if needed)
  
• Disassemble/clean/reassemble
  
• Sandblast clean
  
• Valve lash set
  
• Pressure tested to ensure no leaks

Stage 2 includes all of the above, as well as:

• Completely ported and knife-edged intake ports
  
• Completely ported and knife-edged exhaust ports
  
• The extra porting and knife edging results in a larger port that is more consistent than the stock port, resulting in smoother power and better airflow.
