new holley 600

Just ordered the Holley 0-80457S 600 carburetor the one that has the "next gen" needle & set design that eliminates the need for external float level adjustment. I'm putting it on a 85 mustang the carb is suppose to work with 4-6 pounds of fuel pressure I see the 85 had 6-8 pounds. Is anyone using this carb in a 83-85 with out having to get a fuel regulater

do you have to adjust the floats on it yourself. i've got holley on it know and had a capri with a 600 holley but they where the type that you adjust the floats on it your self. The one i just got is a non adjustable type to make it easier.
