headers on a 69 dart

hey guys need your help got this 69 dart it has a 318 but it looks like it was a 6 cyl. trying to make some repairs. it has headman headers. now here's my question trying to pull passenger side header. what i have done so far is pulled center link, took bolts out of trany cross member put a small jack to hold it and took nuts off motor mounts to lift engine. so now how does it come out. any advise would help.
