The SCs didn't come with them.
If you have seen picks of the rocker shaft you will see two grooves in them. The o-rings fit into these grooves to help seal the shaft. Normally, torquing the shaft will cause them to expand and seal. However, on a rebuilt engine it becomes less likely that they will form the proper seal - hence the o-rings.
