273 rocker arm adjustment

i also still haven't figured out what i am going to do for push rods...everyone online only has 9 of the RP-3159 push rods, so that must mean they are getting them from the manufacture and that all they have? i dont know why its so hard to get these push rods, there has to be something else out there available? I dont want to change the length either because i am getting a really nice pattern on the rocker tips. I need to get some push rods by next weekend so i can get this thing running.
