What is the best kind of Jet needle for the SU carbs?? I have heard that the British SM needles are the best, is that true? I have 72 carbs and the Automatic Trans Needles on my carbs if i were to change to the 70-71 carb needles would it add any HP or Performance???

Please Need answers...

The '70 needles will gain you some power on the top end above 5000rpms. The SM needles are about the best all around, by far better than the '70 needles. The SM's, a ignition upgrade and a fuel pump upgrade will get you about 10-15hp, maybe more depending on application.
