With the manifold - why dont you get the crack welded up - have the face skimmed to make sure its flat - clean up the head - and then whack a new gasket in place inbetween and take it from there. I cant see it leaking after that unless you're really unlucky!!! You can sometimes get away with just having one stud missing dependant on whereabout it is in relation to the manifold!!
