You be a luck Y Guy. 
The rockers were pressurized and this caused major flooding of oil at the bottom of the head and at idle, puffs of blue smoke when the car started to move forward.
An  Allen wrench was used to remove the screw in the passage way and the tube(s) were installed.
No more flooding. Even with the valve cover off, oil doesn't run over the bottom of the head and when moving forward from and idle, no puffs of the blue sh!t.
