I have just replaced all my tappets, valves, springs & cylinder head. I got my tappets from the states & it was cheaper than buying a set from GSF, VAG or Eurocarparts. My engine sounds so sweeeet now. Make sure when you put the cams back that the slots in the ends of the cams are perfectly horizontal with the surface of the head in that you should be able to insert a flat metal plate to keep the cams still. Good Luck
