Yeah, and I inspected it myself after the work was done, a lot of material came out with really smooth results. I don't think I ever pushed it beyond 5.5K before I got it, power peak was at around 4500 and started falling after that so there was no use pushing the engine further.Did you ever put on the "performance" head? Results?
Ashamed to say, I forgot all about the needles for the last 18 months give or take :facepalm: current carb needles have about 200k miles driven with themThis will be compatible with your SUs, which should have KD needles fitted.
