This is a set of aluminum cylinder heads off of a 2005 Audi Quattro S4. The engine is 4.2 liters and the heads have five valves per cylinder. The cylinder heads came in for a valve job & surface along with possible replacement of the valve guides if they are worn in an effort to reduce the engines oil consumption. A set of positive viton valve stem seals will definitely be in order upon re-assembly.
