How does a W2 head oil the rockers/valve train?

thanks guys,
I just got the motor running (had a wiped out ball/socket on a push rod #2 cylinder) and i was looking though the oil filler hole and noticed the # 1 cylinder rockers aren't getting oil, looked further down and # 3 was fine.
I'll have to pull the valve covers back off, run it to see which ones aren't getting oil.
Might have a bushing spun in the rockers.
