gusc,
As for easy outs, I use the square ones from
hanson or ACE .Never use a spiral one .

I heat large areas or castings with a large
propane torch (looks like a weed burner-probably
is ). Build a fire brick oven around what you are
heating with a hole in it to put to propane torch
thru. Partially cover the top with brick leaving
enough room to access the area to weld , When done
post heat and I use an asbestos blanket to cover
the brick while cooling. Takes about 10 to 12 hrs
to cool to touch.

I had an alfa-rameo (spelling) manifold to weld
about a month ago, seemed like it was ceramic
coated , had to grind off the coating then weld.
The cast was miserable to weld ,but it does weld.
Email is in the web site .
