New to the buick world. Are these a good header? Would they be suited for a Te44, 3" THDP, 2 1/2 exhuast, SLIC, 60# injectors and a few other minor mods?

The ATR headers have the support rod that connects the PS flange to the PS collector as part of the upper bolt hole on the #2 port, whereas the GN1 and the eBay headers have the support rod welded to the flange and not the upper bolt hole.
The high polish finish says knock-offs. Even if they were the real ATR headers there is no performance gain for your application. The stock headers fit much better, and took my car into the mid tens before I changed them. If your stock headers are in good condition there is no need to change them.
