TBH i had only read about and seen pictures of how to take the head apart but as long as you have a few decent tools around you (and a massive bar for leaverage(i dont think iv used any of my tools as much as iv used that massive bar)) its fairly straight forward.
As for space make ample room, another good tip is as you dismantle, label and place the parts somewhere in the same layout they were in, cant really go wrong.
only specialist tool u really need that i can remember atm is a torque wrench, any decent sized even halfruads tool kits will have all the sockets and extensions you'l really need.
