Need to know what jets and rods to run in edelbrock carburetor.

i have dual fours on my 273, i used the stock afb carbs, they flow 462 cfm each. anyway mopar tune tips says to remove the vac spring from the front carb, close the curb idle screw, on front carb, screw in idle screws. on rear carb, change the sec jets to .063 remove the air valve blades above the sec bores, both carbs. it works, just food for thought. engine runs off the rear carb.i have progressive linkage.
