trentw,
Welcome to the Stovebolt. On your engine, oil is supplied to the rocker assembly from the oil distribution valve which is located on the drivers side of the engine, mid block...right under the header pipe.
You will see a VERY small copper line the disappears into the side of the engine. This tube passes through the water jacket, pops out under the side cover on the passengers side and travels up through the head to the center oiler.
This system is prone to plugging, especially after a engine has sat and might have gotten cruddy inside. Repair kits are made for it...don't try to remove the tube to clean it. It is a one time deal..removing it usually will destroy it and a new one will have to be installed.
You can troubleshoot it by removing the fitting at the center oiler to see if oil has made that far. Many times, the rocker shafts themselves are plugged tight.
More folks will be along to add their advice, and in the meantime, I will try to find a nice link or picture of this system that will hopefully make more sense than my ramblings.
