The long awaited SpeedCircuit Heads for the 2.0L Protege are now available! These heads will flow up to 71% more air at certain lifts over a stock head! All SpeedCircuit heads are completely stripped down and rebuilt, including new parts where necessary. There are two stages of heads available.

Stage 1 includes:

  • Special five angle valve job
  • Bowl work to blend the stock machine cuts into a larger bowl
  • Resurface
  • Disassemble/clean/reassemble
  • Sandblast clean
  • Valve lash set
  • Pressure test 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.
