What's your best guess?

If you don’t mind please give me your best guess as to what I should set the timing to:

I am getting ready to set the timing on my 402 Mopar crate motor (specs are below). I was given the below timing suggestions as a starting point:

18 degrees at idle
16 degrees at 3200 (34 degrees total)
12 degrees at 12 vacuum

The motor is in a:
’68 Dart
A833 four speed
4:10 rear gear
P225/55/R18 rear tires on 18 inch wheels

The Motor:

9.0:1 compression ratio
Big valve Magnum R/T Cylinder Heads
2.02" intake and 1.625" Exhaust Valves
