IE CNC Ported 2.7T V6 Cylinder Heads (ASSEMBLED)




* Required Fields



Integrated Engineering is pleased to present our completely remanufactured set of two CNC ported cylinder heads for Audi 2.7T V6 engines.

These Integrated Engineering 2.7T V6 CNC ported cylinder heads are complete and ready to install.  You will receive the set of two heads fully assembled with Ferrea +1mm oversized valves, Integrated Engineering valve spring & titanium retainer kit, Integrated Engineering perfromance valve seals, and Intergated Engineering valve guides.

Integrated Engineering CNC Ported cylinder heads provide 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.


As the flow table above 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.

reliable performance

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 the 30V 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 V6 cylinder head set on the market. Our CNC ported cylinder heads offer 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. Continue reading below to learn more about these design features.


Highlighted Features

  1. LiftMAX Valve Job

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.

  1. Complete Remanufacturing Process

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.  

  1. Valves (Included in assembled heads)

The stock valves found in 2.7T cylinder heads were not designed to withstand the punishment of larger turbo setups and are a common failure point. OEM hollow valves can split and the valve head can separate from the valve stem. To solve this problem we incorporate fully forged Ferrea +1mm valves. By using +1mm valves, and re-cutting the valve seats, we can ensure that the valve install heights are correct.

  1. Guides (Included in bare & assembled heads)

During the development process we determined that using the OEM valve guides would not be sufficient. When remanufacturing a cylinder head it is extremely important that valve guides are replaced. 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.

  1. Valve Springs and Retainers (Included in assembled heads)

In high RPM applications, stock valve springs are simply too soft and may result in valve float and misfire issues. By upgrading to an Integrated Engineering spring and titanium retainer kit these issues will be eliminated. Integrated Engineering valve springs are the best available and are wound from ovate wire which reduces stress levels in the spring. Our spring and retainer kit resolves rockers arm and retainer clearance issues, which are very common in this application.  


Core information

We require a good usable core big port 2.8L heads to be sent in for porting or a core to be purchased. If sending in core heads for machining, use our inspection and exchange form found HERE to confirm that it is usable and for instructions for shipping your core to us.


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.
