Compound cuts for inlet manifold

[Ashtonr]

Someone please put me out of my misery, I have now cut up about 2 meters of steel tube trying to get the correct angles to make the inlet flange of the CVH meet the inlet spacing of the ZXR6 carbs I have. I am trying to cut these tubes using a miter saw set at the horizontal angles I need, this works fine all the holes line up perfectly but then need to set a vertical angle between the two plates of 30 degrees to allow the float bowls to sit level. I have tried putting the tubes into the miter saw at 15 degrees off level at each end and making the cuts and also by changing the phase of the cuts by 30 degrees and many other permitations but nothing works. Does anyone know how to di this or of a website or program that would help me create a paper template to wrap around the tubing etc ?
