Williams Header install

I am fitting my Williams headers up along with the Offenhouser manifold. I understand the hold down clamps have to be modified to get equal pull on both manifold and header. I did not disassemble so not sure about the order of the clamps. Looks like the two small ones are on the outside while the four bigger ones run in the middle four holes?

Just want to verify before I start grinding on stuff
