More thoughts on using gasket maker on the gasket.

I would not use roofing caulk, its not designed for high temps (engine high). Loctite instant gasket is approved up to 400dF, so I would use it if you feel the need to use something. We use it on our test rig, and that stuff never comes off, so my thoughts are to use no caulk on the gasket, as the original lasted well into the 100k mark for me. That way the next time it will come off really easy. If you use something like that, you will have to use a wire brush or scraper to get it really clean which makes it more likely to scar your mating surface. The old one came out without any troubles, and I reckon I could do the job again in about 2 hours. My 2 cents, feel the difference between the gasket you pulled and the 1 your putting in, they are not even the same material anymore. The new gasket should do the trick fine. If you need to use something else, I would go with an industrial gasket maker designed for oil and the temps were subjecting them to. That will hold well enough.
