I just went through the whole thing... There is more than enough information and relevant pictures I would think

Sit down with a pencil and paper (OMG, oldschool much!1!!) read the whole thing, start taking notes, drawing diagrams etc and post if you need more info... It's not really something you can write a definitive guide on.

yeah, LOTS of good info in there regardless of pics.. ive read through it before. basically you will want a steady hand if your doing this. also patience, take your time to do anything. the faster you move the faster it goes wrong. what plans did you have? bigger valves?
