I believe Poorboy is right. FMS does not always ensure their distributor curve is wide enough to start at 12 degrees and max at 32 degrees for the 20 degree advance. It is a quality control issue. My crate 351W had the same problem. It should be at 13 degrees initial and 36 degrees max. BUT at 2200-2400 rpm (or less)your distributor will have already opened the weights and the max advance should be in at 32 degrees. Therefore, you motor was "power timed" at max advance at 24-2500 rpms to ensure proper race performance at all higher rpms. I time my motor at max advance 36 degrees at 2300 rpm and let the initial timing fall where it may.
I considered having my Ford distributor recurved but was advised against it because my motor runs great. The MSD distributor has both adjustable initial and max settings but that is another expense. You may just leave the motor timed as you had it done.
