Ended up having no luck with the exhaust manifold gaskets. Pulled one apart but the indent pattern is different between the two so gave up. A few more shops should be open tomorrow so will try my luck but pretty much resigned to dropping the engine in without them attached.
Put that to the side and got onto fixing up the steering coupling. Somewhere along the line it got gifted with this masterpiece from Ireland Engineering. Can appreciate the intention behind it but what an absolute piece of sh*t it is. I suspect it would be around 4-5 years old but already very soft and insanely squeaky.

Compare that to the stock 20-year old rubber one from the engine donor car that still feels solid as (the cracking is coming from my wrist...)

If anyone thinking of doing this "upgrade" ever happens to see this - DON'T.
Got the parts nicely cleaned up, put a dash of white lithium grease on the pivot points and bolted the thing up. Did have to drill the holes a size bigger to fit the M10 8.8 bolts.
Was going to put the heatshield back on to make it a bit less conspicuous but that was just too mangled up to be of any use.
Haven't looked into what the cert/WoF verdict might be on it but can easily throw on the original spare coupling if they deem it an issue.
Otherwise, the freshly cleaned heat shields all bolted up, pretty much set for the engine install. Have a mate coming around tomorrow to help with the manoeuvring. Really regret not getting the AC system drained prior to this whole endeavour as that'll be a bastard to dance around but... will manage.
Tomorrow is the day.
