I did this to my Toda mani. It's a fiddly job so take your time and don't rush it. Dampening the wrap with water is supposed to make it easier to apply but I'm not sure I noticed much difference tbh.
IIRC I started from the top of the primary (nearest the head), went down to the first collector and back up the mated primary, then finished the bottom part of the manifold off separately.
There's not much space between the pipes at the bottom end so this is where you have to be really patient.
Hope that helps - best of luck!
