Yeah nice work, made it look easy and inspires me to have a go in about 3k.
At a guess I'd say about 6 to 10 hours depending on skill, and requires the following:
Full set of Allen keys and sockets 1/2" drive
General stuff like screwdrivers, pliers, hammers, feeler strips etc
Doesn't look like any special tools req'd (pullers, jigs, etc)
Oil change gear
Shims (they look like Ducati parts not just caps that house shims)
Gasket kit for both heads and anything else that had a sealed flange
Thread locker, probably red, as there were no lock tabs or other retainers
Oil filter and new oil
A copy of those photos
Multiple viewings of the youtube demo
Pages from the workshop manual with torque settings etc
Six pack of beer for when it's finished
One question: your adjustment was only a couple of thou, did you notice a difference as a result??
