Product Summary


This Integrated Engineering Audi 2.7T 30V V6 CNC ported cylinder head does not include valves or springs and retianers.  You will receive the cylinder head machined, CNC ported, and complete with IE valve guides installed. If you would like the head supplied with valves and a spring & retainer kit installed, see our CNC assembled head (IE Part number: IECHVD2). 



We require a good usable core head to be sent in for porting or a new cylinder head  to be purchased. If sending in a core head for machining, you will be emailed an inspection and exchange form with instructions on how to confirm that your head is usable as a core.



The Integrated Engineering CNC Ported cylinder head provides large power gains from the middle of the power band all the way to redline. Large airflow increases are obtained by a combination of changing the port shape via CNC porting and re-cutting the valve seat geometry. We worked closely with an industry expert who has over 30 years of OEM and professional motorsport experience to deliver these results. Street drivability was preserved by careful development that does not sacrifice torque and airflow velocity. 

From the outside of the head all the way through, our ported head delivers performance. The intake and exhaust ports are masterfully crafted to deliver maximum airflow without sacrificing torque. Our proprietary LiftMAX valve job was specifically developed for the unique conditions found in a VW / Audi engine. It gets the most airflow from the small valve lifts and bore sizes which are unique to these engines. These incredible gains are only possible through the combined efforts of modifying both the ports and the valve seat geometry.

The end result is the best performing 2.7T cylinder head on the market. Our CNC ported cylinder head offers the maximum power increase at an incredible value. You will not find another head on market that includes all the features and extensive machine work found in this cylinder head.



Integrated Engineering’s LiftMAX valve job is designed to extract the most power and flow from our CNC port design. The LiftMAX valve job accounts for application specific factors such as small cylinder bores and relatively low lift camshaft profiles. Placing a strong emphasis on the valve job is essential to get the most out of any CNC port before air enters the combustion chamber.



When it comes to performance cylinder heads, a complete remanufacturing process is the only acceptable method. Integrated Engineering does this by completely stripping the cylinder head, unplugging and then purging all oil galleys, and removing valve guides prior to CNC porting. After the porting process we install new Integrated Engineering guides, skim cut the cylinder head deck surface to ensure a perfect head gasket seal, recut the valve seats for Ferrea racing valves, and then perform a final quality control inspection.  





During the development process we determined that using the OEM valve guides would not be sufficient. By porting a head with OEM valve guides installed the overall length of the guide is shortened which results in valve stability issues and increased wear on both the valve seat and the guide itself. To remedy this, Integrated Engineering installs new guides after the porting process. Integrated Engineering guides feature a proprietary alloy which improves wear resistance and heat transfer from the valve to the cylinder head. These two factors result in increased longevity of your valvetrain components, as well as decreased knock and more power.


As the flow table below shows, the Integrated Engineering ported cylinder head increases flow up to 29 CFM on the intake side and 35 CFM on the exhaust side. This results in a flatter and longer powerband that will take your 2.7T V6 engine to another level whether on the street, drag strip, or road course.

The IE LiftMAX valve job is designed around specific Ferrea oversized intake and exhaust valves, no other valves can be used.

  • Required intake valves: F1557P

  • Required exhaust valves: F1555P



Although other valve spring & retainer kits will fit and can be used, we highly recommend using our IE 2.7T valve spring & retainer kit with our CNC ported cylinder heads. IE valve spring & retainer kit features specific spring and retainer designs that are perfectly matched to perform reliably with our LiftMAX valve job, Ferrea valves, and cylinder head port design.

  • 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 “dropping off” 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 big turbo 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.

  • What valves do I need to run with these ported heads?

Because our LiftMAX valve job is designed around specific valves you must use Ferrea +1mm intake and exhaust valves. The part number for the intake valves are F1557P and the exhaust valves are F1555P. These are also sold separately on our website.

  • How important is a performance valve job?

Extremely. Many of the gains achieved through the CNC port design would not be fully realized without our professionally applied 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 Audi 2.7T and 2.8L V6 engines found in many Audi vehicles from 2000-2004.
