Leaking brakes, re-flare?

When I first got my 74 Dart Swinger with manual brakes, the brakes were awful. So replaced the master, distribution block from Mancini, all brake lines with Inline Tube, front rotors and pads with drilled/slotted, replaced front caliper seal, new shoes on rear and rebuilt drums….. and the brakes felt the exact same, except now the distribution block leaks, yay!

I could not tell which line was leaking before I took them all apart. I was expecting to see a flare smashed in the dist. Block sideways but all look ok. I had them cranked in there with a line wrench too.

What should I do? Cut and reflare all the lines? Get new lines, again? I have attached pics in case someone with more experience sees something off.
