Hi there, I race the Citroen AX 954cc. What I was wondering is if anyone could help me find really technical information on them. I'm after things like cylinder head casting numbers and which ones are better. I have asked around and I can't seem to find this high level of information off just anyone. If you can help me and give me your advice or maybe even direct me in the right direction I would be truly grateful. Regards, Gareth Edwards gaznw43@hotmail.co.uk
