Hi all, This is my first post so excuse my noobness! I have a A3 1.8 2001 (121000 miles) and the cambelt has snapped damaging two exhaust valves, whilst stripping the head out i have noticed pitting and flat spots on the cams, so got looking for parts and costing it all up became expensive very quickly! My question (i hope not a stupid one!) is ive found a AGN head all complete but mine is a APG head, will it go in or are there differences between the two? Thanks in advance.
