put a really good 9 way adjustable timing set in it so if you need you and take that 108 cam down around 102 to 100 if needed for banking.
use a electric water pump and a crank driven fuel pump with a emergency shutoff and by-pass
use a magneto for ignition, you going to need all the output and reliability you can get
if you don't have the hilborn yet, I would you a duel rons flying toilet injection, more reliability and better adjustability plus its not remanufactured from 40 year old parts and will cost you the same money
Fire slotting domes with Alky gives you a better solution.
I agree with everything else you posted.The thing with Hilborn is it is a combo between the balance/set-up of the car,the gearing of the car per track,and the correct pill size.A weather station and a log per track helps.Depending on how sharp of a tuner you are,that data might take sometime to gather.You want to change one element at a time.Read the plugs constantly.Leakdown every wk as apart of normal maintenance.Valve lash every wk.Catch a problem before it becomes one.Good data will pay-back a thousand times over.Open up the ring gap the same way you would with any other power adder.
We have never used a aftermarket block in any of our 9.90 or 10.90 cars where in both we have used Alky. They get freshen up at the end of the season along with the above routine.
