If anyone is interested, I have my original German AAZ head which I really don't need. It has the usual valve cracks. It is most likely warped as the engine got hot going up passes when I first installed the engine. Pre-chamber #4 is very loose, and should be peened in.(Probably should do the others as well) It is bare other than guides(8mm) 7mm guides could be installed as the valves are much easier to find than the 8mm. The camshaft has a messed up #1 intake lobe, but it could be built up and reground. It was from when my TDI broke the lifter. Make me an offer on either or both. otherwise they get sold for scrap as I have too much crap laying around.
