Good.
Now on to tayloring the curve/setting initial & limiting the mech advance.
I'd start with 1 blue spring and 1 silver spring, then take a small 1/4 nut and grind it to be the same width across as the black bushing that comes with the MSD distributor but leave it longer the other way as to take up some more of the slot. From there you just check the mechanical advance with a timing light [dial back style prefer'd] grinding the length of the nut to the desired amount of mechanical advance you want.
The more you grind from the length, the more mechanical advance you'll get.
