No no no, wait.!! Just move the number one wire over one post on the distributor in the counterclockwise rotation, and all the others accordingly.

By doing this you will have advanced your timing some 45 degrees which will be about 25 too much so then you will be able to rotate the distributor clockwise 25 degrees which will be perfect.
