Check the hight of the hole against the dam where the valve tapet is. There was a dam where that hole is that let oil flow to the timing gear, however it became popular in the 70's to smash the dam out with a hammer to allow more oil flow to the timing gears. While most peolpe that did this didn't have any problems, there was a side effect. You see sith that dam smashed the oil didn't get high enough in the valve chamber to allow the desired flow to the rear valves, as it had to over come all the seperate dams within the valve chamber.
