Yes, a little while ago me and my friend Raoul drove to Germany to have a look at some used cilinderheads for my rs4. The old ones needed t be replaced (check www.rs4biturbo.com for more info on that topic).
So we drove about 4 hours to check out these cilinderheads. Great dress for getting some good used parts. I bought them and had them overhauled at Van Rijn
