How does the head tube behave when the frame is welded up? Is there so much distortion that you have to re-surface the bearing seats or is the tubing thick enough to render it moot?

(I'm used to "thin" tubing {0.035} and even with the use of heat sinks there's enough distortion to make post-weld machining necessary)
