I managed to remove the cylinder head from my RHD S4 last night, and it only took 2.5hrs. I don't think it's been off before, but with the help of the lifting tool it was a breeze. There was little corrosion on the head studs luckily. The engine has done 90,000 miles, and was a little tappity when hot, and would also burn oil on the over run. I am going to take the head to Hamlins machine shop in Bridgwater, and get them to check it over , fit new guides and anything else. Is there any point in going to three angle valve seats? The cylinder bores look really good, the performance was always fine anyway. I did notice that the return pipe from the fuel rail had completely folded and collapsed into itself, this couldn't have helped fuel delivery so will be replaced. The engine and bay is going to get a degrease and cleanup, and the rad will come out for a rebuild/paint, and i will replace the power steering hoses, which are starting to weep. Then i will repaint all the black painted items in the bay, and polish up the ally bits, should look much smarter then. So not much to do!!
