Is it possible to replace the hydraulic lifters without taking the timing chain cover off and all the extra work involved with that - new bolt for crank pulley, remove engine mount, really awkward location etc. If I just remove the chain tensioner would that be enough to remove the cams?

You could try bungee the pulleys up to a bar of some description to keep the tension on. Your biggest problem is if the timing jumps and you don't realise.
I'm presuming you are standard or stage 2 SC with standard cams ?

I've heard that the sprockets will still move on the pin when you disconnect them from the cams.
I changed the valve seals by doing so, but only loosened the chain tensioner, and took one camshaft at a time and had no problems.

If I'm wrong and they are z22se I'd definitely cable tie the chain to the pulleys as the procedure in the video bares very little resemblance to actually working on a real engine in a real car. 😄 (I love the way things just glide apart with no shite in the way and with no need to do a Mr Fantastic impression ðŸ˜) The chain is unlikely to jump on the bottom crank sprocket as long as you don't drop it but I think something set up with bungee chords would be more reassuring than leaving them hanging on the timing tool.
Only use genuine GM lifters - I tried to cheapskate it in the past and they just couldn't cope with high performance cams and went noisy within a few hours of running.

I can't remember the brand, something like BGA or IVA, but I doubt they manufactured them. Pattern parts like this probably all come out of the same factory and get branded up by various companies.
Unless someone else can chime in with a brand they know works OK with stronger springs just bend over and get GM.
