mounts for a b16 swap in a 1983 hatchback

I am looking to put a b16 into my 1983 hatchback. it's a 1300FE and i think the motor is on it's on its last leg. It has a lot of valve chatter and i think it is on the verge of bearing knock. What all is involved with the swap?... i know i need to run a stand-alone, custom mounts and the obvious stuff like that but does any custom framework have to be done? exhaust manifold?
