If you read thru the various engine articles in the tech archive section of this board you'll pick up some tips. Start with this one:

start with 92 all round --always keep it square jetted--a very good set up that is efficient can use less jet--you may need less to keep a bracket car from picking up when the air gets better at night and when the summer comes but 92 is a good starting point

Basicly treat a 4500 series carb like 4 one barrel carbs that just happen to be connected to each other, not like a 4150 that has primarys and secondarys. like said before, jet them square, don't adjust Idle speed with just front, spread evenly all the way around. It will be happier that way.
