How to install rocker studs included with edelbrock aluminum rpm head?

It appears as if I have to install the 2 rocker studs along with the hardware included on my edelbrock aluminum performer rpm heads. In the installation instructions it doesn’t explain specifics on what hardware goes where when installing the studs, washers, nuts and what appears to be spacers on the heads. There are two rocker shaft pedestals that have to be fitted with the hardware and I need to know in what order the parts go on and where? I have included two pics. One shows the rocker studs and hardware and the other shows one of the rocker’s pedestals it goes on. Any help appreciated.

Looks to me like the two big washers are for the shaft itself to help space it I believe but it's been a long time since I've last touched a set
