I would say drive it as it is for year or two. Once you've got a good few thousand miles under your belt, then you'll have a much better idea of how you want your car to be.

I understand you very well. It's a lot of fun to equip, enhance or beautify your Morgan. But if you allow yourself a little time, you can appreciate, classify and enjoy the result much better in a year or even in two years.
Personally, and later on I would start with the smaller things, e.g. brake reaction bars, maybe a K&N filter insert, high octane fuel, later then adjustable shock absorbers, etc. I would never start with single throttle valves, that would be rather something for the last measures.
An honest question, are you satisfied and can you enjoy your car as it is. Or are there already areas that you would like to change because something is bothering you? If not, take it easy and just enjoy her.
If you play music, imagine you've been playing guitar for a year only, you can't really appreciate what distinguishes a 1961 ES335 from a 2018 Indonesian Epiphone. That's just a comparison, and I respect your desire for development and change very well.
