XT 190 oil lines uder valve cover!!

Hi everyone! thanks up front. I bought a basket case last winter.It is a 1969 I think AC XT 190 Diesel. I rebuilt motor,New sleeves,pistons,rings,ect. i even had $600 in head. Ok , I have all back together except, I dont have the oil line under valve cover that feeds the rocker arms.Most I have seen,have a line that connects to head,and goes to rocker arm shaft. I guess they are hollow,for oil to run through to oil rockers..This one Is not like that.It has a oil line  male connection under vavle cover,and has 6 oil line connections by the rocker arm bolts.they are female. I take it a line runs from head and down the rocker arms full length,and T`s into each 6 connections! Im stumped.Is this a later head on the XT or what..Thanks Guys....Dave

Ok Ill look at this.But I dont think my rocker arm shaft is hollow! Ill go check it to day.IF it does,,I guess I would plugg the other holes.Thank you

If you really look, there isn't any holes in the hollow rocker arm shaft except for the very front and the rear like I said in my earlier post. Each rocker arm support has a hole because they are all the same part in all six locations but only actually use the holes in the front and rear.
