Precision CNC Machine Subaru EJ20 Cylinder Head Combustion Chambers to EJ25 specs for installation on an EJ25 Short Block Assembly, commonly called a ' Hybrid Build '.
* This service does NOT include Head Casting, Disassembly or Assembly, Precision Multi-Angle Valve Job, or Resurfacing. This is for the Porting Service Only. All other machine work is extra charge.
* Please note, It's not uncommon to see certain parts of the ports that are not machined. This is because with most of our port designs we try to keep port velocity to a maximum, It's not always about how big the port is, or maximum flow numbers. This almost always helps with low to midrange HP and Torque numbers without sacrificing top end.
