Ok, so that video may be on hold for a few weeks. I'm thinking I might get the head rebuilt while all of this is out of the bay again, since the valve seals are a bit suspect and it's due for a timing belt in 10k anyway, so I'm erring towards just fixing it all for good and not having to bugger with it again. Bottom end is still alright though, so I'll just replace the crank seals and re-do the sump.
