Default Dorman exhaust manifold

So I see mixed reviews on these. I'm not like inking for performance, just to fix the problem. Are these really as bad as some say?

The exhaust manifolds are decent...I've read to just make sure everything is aligned properly before torquing it down. They can bind and cause stress fractures according to DanielYaegerFilms.

I replaced mine with Dorman about a year ago. Good for the price. No leaks. Although I did use Motorcraft gaskets.
