Default Thermo-quad Tips

I am attempting to build my own Thermo-quad for 72-73 340. I don't want anything on it I don't need
but, leave or modify everything I do. Is anybody willing to share any tips on successful modifications?
Fuel pressure?
Is the vacuum diaphragm on right rear necessary to regulating air door?
Is converting to Holley jets and removing the metering rods from primary circuit the best?
Is removing the choke S/S legal?
Is a -6 inlet adequate for fuel delivery at say 530 HP?

I've read about 40-50 HP differences in modified Thermo-quads so, there must be some things that work better than others.
Thanks
