The thread locker I used specs to 450* max temp, which isn't as high as I would have liked, but like I mentioned, it is what I had on the shelf.
I have used Permatex Ultra Copper Maximum Temperature RTV on my Harley exhaust system, which is rated at 700* max temp with good results. I wanted to use that on the threads but couldn't find it. I'll try that in the future if I have any leaks.
I media blasted the manifold and coated it with Eastwoods exhaust coating. It looks pretty good and the small plugs blend pretty well.
