From my limited experience, the only thing I had to outgas and preheat was aluminum items, Such as valve covers and manifolds.

my first valve cover is at www.kiyi.net

I prebake everything as an extra measure to remove any missed oils.After washing I bake it to dry and then leave in about 5 minutes extra to burn clean. Remove from oven alow to cool until you can hold in hand then coat.
