Headers is such a wide debate since there are S O many things to consider.
When you say mild? 1 5/8 vs 1 3/4". Ask you engine builder. I've seen many 11 sec cars with 1 5/8. Bigger is not always better. Also long tubes or full length will alway make more torque than a shorty.
Get a thick flange if you like no leaks. 3/8 minimum.
Thick pipes will be quieter and last longer. Consider coating or stainless steel.
Collector length and mounting. The floating rings absolutely kill gaskets. Ball socket is so reusable and reliable.
None of these good features will be on a cheap header. Name brand only.

If you can't find the ball/socket type cut the flanges off.

This isn't the prettiest but 0 leaks:
