Audi 7A to AAN cylinder head machining service

As the supply of good condition AAN cylinder heads dwindles we took it upon ourselves to setup tooling to convert mostly crack free 7a cylinders heads to be fully AAN compatible. 

To that end we add the additional exhaust manifold studs, machine the water manifold ports and add the cam sensor provision to the front of the cylinder head.  All heads are pressure tested washed and surfaced after machining.  This is a core exchange process using your 7a cylinder head. 

We do have cores available as well.  Select from the options. Note that additional repairs may be required upon examination of your core.  Any necessary servicing will be discussed in advance.

Be advised that if your head needs additional work (exhaust valve guides are very typically worn out of spec on higher mileage heads) there are additional charges if your head requires guides. 

Heads are harder and harder to come by so check in with us for current lead times.

Allow 3 weeks for servicing if we are machining a head you supply
