You're definitely well on your way.

Those look like 346 head castings from the "II"....

Don't forget the Mallory Rev Pol, Voltmaster coil, paint the headers white, etc etc. Or maybe Accel dual point + super coil + yellow plug wires that always seem to be covered with grease stains. Definitely consider using solid core plug wires to cause as much radio interferance as possible. That's how they did it back then....
