Thanks for your replies. I managed to speak with Ken, (he's closest to me), and he has been very helpful in clarifying a few facts. So far so good, looks like my engine choice will work for the latest 2005 regs (phew!). With respect to Bathrone's comments - appreciate your frankness and I totally agree with you - I wasn't looking for an "easy" engineer, rather somebody who is experienced in ICVs such as Cobra's. I guess I should of phrased my original question a little better. Thanks again for the advice.
