Anything with a 3/8" thick flange. Avoid the thinner stuff.

The Mopar exhaust ports 1, 7, 2 and 8 are sealed up by 2 bolts. One on each side of the port.
The middle 2 ports are sealed up by only 2 bolts with nothing in between. A thin flange will often leak in the middle as the flange warps.

You will hear 15 stories about how a couple guys got a cheap header to seal but the fact is thick flanges seal every time.
