Keep the 1406 Edelbrock or switch to a 1403

A previous owner put a Edelbrock RPM Air Gap and a 1406 600cfm carb on the 305 in my 85 Silverado. I know the air gap is too much for it and the 600cfm is a bit too much also. I am going to switch to a Edelbrock Performer EPS and maybe a 1403 500cfm carb. My question is can the 1406 be tuned down to be more 305 compatible or should I buy a 1403? Thanks for any and all opinions.
