HEI advance curve ?

[robby]

I have a 307 with a quadrajet, dual exhaust, later model 305 heads stock automatic and 3:08 rear end in my 70 C-10. I looked at my HEI when I replaced the cap and rotor and saw that the bushings on the centrifugal advance where gone. I bought an advance curve kit with new springs, weights and bushings. It shows 3 curve choices. They come in at about 1,000 rpm, 1,800, and 2,500. I have no idea which to use. This is a daily driver, but I woudn't mind more throttle response. Please help.
