I can not say for with out actually seeing your motor running but 6 cylinder chevys do not require but very little over head oil. With the valve cover off and running, you won't see much oil at idle--- nothing even close to what up would observe looking at a running V8 motor. In fact too much overhead oil on 216-325-261 will cause the rocker cover to over fill and oil will spill into the valve guides.The area that handles the return oil in a chevy 6 head is very shallow in comparison to most motors.I have found when I start a fresh 216-261 motor that it is best to leave the rocker cover off and put all but about a half quart of oil in the motor. Just a few minutes before I start the motor I pour the remaining oil over the rocker shaft, then install the rocker cover and start the motor. I have heard some unusual noises on start up because the rocker shaft is about the last thing to get good oil flow.
