These triangles are being brazed while in a fixture, or held freely in space?

If it's a lugless assembly, or even if it isn't, and you *want* to buy back that missing .7 of a degree, simply add a millimeter or too to your fork span.

Or, next time - assuming this is a trend - don't trim the bottom of the head tube and leave it long a bit. That'll get you the same result as a longer fork.
