I know it sounds strange but when I did try less initial advance I got better low rpm torque and it idled more poorly. I dont know what is total now, but when i made performance tests earlier I set it to 34
This seems to indicate that your combo is running too much centrifugal advance. You have two choices, well really only one, and that is to slow it down and peak later.
I run 14/34@3400plus 22 ported. Works for me.With 87E10.
But it may also speak to a restricted exhaust. AJ's guide to Transfer Port Synchronization
