Timing help needed

I have a 440 in my dart with a billet MSD distributor. It has a 950 proform carb on it (4150) It has a set of fully ported 2.20 valved RPM heads on it and a roller cam in the ballpark of 255/[email protected], 112 LSA and .650

I know my old convertor is too tight but this thing isn't 100% happy at idle. Timing is currently 18/36 in at 3,000.

MSD's biggest bushing is 20 degrees (black) I found Don Gould makes CNC bushings at 10 degrees and at 14 degrees and ordered a set last night.

Do you guys think 4 more degrees of advance at idle will help? (22/36) and also, is 2500 ok to have full advance or should I try to keep it around 3000?

One of the issues is youhave to create you own spring graph becasue DOn doens't tell you what springs to run. He just says full advance 500RPM under your flash stall.
