FAQ

What kind of gains will I see with this CNC ported head? How will it affect my driving experience?
---Gains will vary with each setup, although gains are primarily in the higher RPM range. Power gains are typically higher on engines with larger turbos and larger camshafts installed. You will immediately notice the power no longer ﾓdropping offﾔ as RPMs increase, pulling much harder until redline.

Why CNC porting instead of hand porting?
--- This head porting program incorporates far more research and development than is possible in a one off, custom hand porting project. CNC cylinder head porting also offers repeatability and consistency that is nearly impossible to achieve when porting by hand. The end result is more consistent flow between cylinders.

What changes will need to be made to my software?
---Although many aftermarket files can self-adapt to changes, custom tuning may be required, as airflow is increased greatly at high RPMS. Please contact your tuner for more information.

Can I use other valves than Ferrea +1mm with your cylinder head?
--- No. Because our LiftMAX valve job was designed specifically around these valves you must use them. Ferrea has over 30 years of motorsports experience; you will not be disappointed.

How important is a performance valve job?
--- Extremely. Many of the gains achieved through the CNC port design would not be fully realized without a professionally done valve job.

Do you ship assembled heads with camshafts installed?
---We only ship cams installed when a customer is ordering a full long block (complete engine). This is to prevent damage to valves that may be extended past the deck surface.

Will this head fit my car?
---This head will fit all 2.5L I5 engines found in many VW vehicles from 2006+
