I would add disc brakes and a dual master cylinder. I have lost brakes before and it is not fun.
That done I would go with the dual out header and true dual exhaust.
Then the electronic ignition.
Then drive until you can afford the new head, roller rockers, cam and 4barrel manifold.
I would consider a collapsible steering column, Flaming River has them, and some suspension upgrades. I also added a three point belt system to mine and on the pre 1969 you may want to consider high back seats (some safety stuff from a dad with 20 year olds).
That what I did and it seems to work ok and I am happy with it.
