It look like the lip here may have been reduced somehow or bent smaller from vibration and heat. IF those bolts came out (strange), it must have been pretty noisy for a while. Don't break any bolts...Just don't.
You may be able to put the flange back on and carefully peen the pipe to seat in the flange here.
need a gasket in addition to the bolts.
You may need thses at the manifold:
