Removing Nav station-Stove Sink Area on 77

I'm considering removing the nave table area on my 77 E-32 to replace all my seacocks and valves, as well as evaluated my engine mounts and rear engine area. Has anyone done this and what am I in for? It's pretty tough servicing that area properly due to space limitations and I'm thinking of pull it apart when I do my bottom in a few weeks. Any input would be appreciated.

Thanks in advance to anyone who relies!!!
