Do a combo of all suggestions. I like wheelspins wax trick going to try it on a manifold fitting soon. Put your jam nuts on before hitting it and lock them on with some red loctite and let it set up a day. Soak it down good. Try using an impack gun rather than a rachet or wrench for less leverage for bending. Set your air pressure a little low to see what happening and how it feels before going all out
