CBR F4i not starting (video & info inside).

You forgot to add that higher octane doesn't give you any more power or fuel efficiency either, assuming the engine is designed for 87. A lot of myths floating around out there, many times spread by people that should know better.

I would also be inclined to say the shop did not pull the head. I imagine if they did, they would replace the head gasket at the same time. That makes me wonder how they unseized the valves.

They didn't at that price. Probably removed the intakes and exhaust and cleaned from there. A hammer with a punch and cleaner / lube will generally fix sticky valves. If things were gummed up enough to cause the low / no compression issue shown in the video the proper way would be to pull the head and recondition. Doing it that way would have cost the OP a lot more than $400.
