If you're not in a cold climate enviornment, you can lose the cold start valve. The anti backfire/ decel valve seems optional, mines off and runs fine. Your aux air valve isn't needed to start the car, many of them are seized and not working on others. The key items would be the brain, dual relay, resistor pack, CHT, airflow meter and a good rubber boot.
.....And of course, no negative air leaks
