Header Flange

I have an old set of headers that are in pretty good shape & I'd like to have them coated & use them. Main problem is the 3 bolt collector flanges are bent from over-tightening them. I was thinking of using a set of these & am looking for opinions on them. They seem like a good idea, but those have been "Famous Last Words" more times than I can think of.
