Filling with aluminum you still get heat soak.

If you want to prevent the paint from burning, do the same what folks do with the exhaust ports, paint first with some Eastwood exhaust paint or other similar product, before you lay down the color.

Pretty sure the POR-15 high heat paint is the same thing:

It's always best to etch before you paint, but you don't have to, just lasts longer if you do. Use a good quality engine paint too, I like Dupli-color ceramic.
