Firecore Distributor Curve/Springs

Mine did not.
Ok, so here is where I am at, it idles the best at 22-23. I have two blue springs on the distributor. My curve comes in at 1800 at is all in at 2600 rpm and 45 degrees total timing. I’m pretty sure I need limit the mechanical? Where abouts do you think and how do the pros feel about the curve?

Edit: Specs might help.

440, 30 over, Promaxx heads, TRW -12cc Dometops, Mopar 296/.557 cam, RPM intake and Schumacher headers with a hughes 2800 TC and 3.55s . I don’t have a measure CR number but cranking PSI is ~160 across the board.
