Have a go Howard. Braising is definitely a better option... I bought a big Hilmor floor standing pipe bender like this...

Then fabricated a 4 into 1 based on a Speedex manifold.

It's probably a good idea to bolt the 8mm plate to an old block or at least a cast iron manifold when you start applying heat! Don't ask me why I didn't the first time...
Work out the shape, bend the tubes, cut them to length then square the ends...
I used a sharpie to reference the location, bodge tape and some roofing batten to hold the shape.
