Don't worry about the effect of heat on fluid, you will be replacing all the old fluid anyway once the new valve is in.
And from my experience heat/cold is more important than any specific concoction of penetrating fluid. Be patient, any movement at all should be used with more fluid and heat.
Eventually it will break loose, but it can take time. I spent a half hour on one fitting this summer. But did the prop valve and all 4 wheel cylinders without a single broken line.
