Restricted Oil Flow Rockers or Pushrods

Right now my 401 is at the machine shop. I have to make a decision about oiling soon. I plan on using the bearings with the smaller holes. I've read in one post or another to use them with the rocker arms that have the smaller wholes. Is there any disadvantage to run the pushrods with the smaller holes vice the rocker arms?

Thanks,

Use the bearings no need for all three you will have too much pressure.
