Broken exhaust manifold tab / ear...

I had a nasty exhaust manifold
leak at middle section, (see pic) with no gasket installed.. Surfaces were clean and smooth. I installed a set of Remflex gaskets and torqued to the recommended 20 ft lbs. I finished up the other side and start to look things over and notice that where the exhaust leak was, I broke one of the ears / tabs.
Does that maybe lean towards the manifold being warped...specifically in the area that broke..? I have another manifold on the way, should I try again without a gasket..? So many different opinions on whether gaskets are needed, or some say Screenshot_20250203_190417_eBay~2.jpgthey cause problems.... What gasket have you used or recommend, if needed..?
