Andrew the oil supplied to the rocker gear is at reduced pressure, if I recall, regulated by a cut out or cut outs in a cam bearing surface. As long as you are getting some to each rocker it will be fine. It runs down the rockers and lubes the valve stems and the push rods and cam followers also.
When you have it running you can check it with the cover off.
It is probably a good idea to run along the rockers with the oil can before starting if they look a bit dry. some rockers will move sideways to get a bit of oil into the bearing surface (hopefully they were lubed on assembly)
