I owe Andrew a few favours after he did a cylinder head for me.. So when I can I plug his work as much as I can. I'm now a Clio 182 owner now with one of Andrews heads. I recently seen the same head work done to a 182 and that broke 220bhp on the Dyno with minimum modifications done to it.. Chip had some involvement in it I believe? I may be wrong. I'm sure he will tell you more about it.
