Id say be prepared , it sounds like the car is well sorted and has made long trips before, so you should be fine but if you are concerned maybe you could trailer it there? I am considering that option, although I drove mine last 2 years and this year it's already been driven 980 miles to CT, then back home 1100 miles as well just 2 weeks ago. I know how well sorted my car is and that is what only you know- I have with in the past 2'yeara replaced all suspension parts, brakes calipers, etc etc etc. no worries there.
Bleed brakes, tune and timing, bring extra parts- fuses, relays, tools , jack, I have an emergency bag with flares, tools parts and may drive all the way, but I have a friend coming with and I just may rent a car hauler to trailer the car on, and pull it behind the truck(Navigator L with full tow package). My car is not as clean and original as yours. If I were you I would tow- if you don't have a tow vehicle, maybe borrow one or invite a friend that has one
Either way hope you make it safe and look forward to seeing your car again this year!
