Got the Lambda and AFR gauge working now. Haven't really done anything yet apart from see how it idles. With the new exhaust I noticed it hunts and drops down when idling, the Innovate lambda's telling me its very weak at tick over. I'll be having a look at tuning the carbs this weekend, even if its just near enough to get back down to Blogg Brothers for a proper set up.
Still need to complete the new inlet manifold tho!

Any, here's some pics of the exhaust I got from AAS in Newcastle. Sounds great, ticking over quite quite but once the revs build and the VVT kicks in it howls... nice!!I've constructed a copper heat shield for the sensor out of 28mm copper pipe as advised inthe Innovate manual.
