200 ci pushrods

ok i have a question that is baffeling me and my old man too. I have a 68 mustang with a 200 ci l6. when i pulled the head and had the block machined i noticed that the lifters have a hole in the top of them. My understanding of this type of lifter with non adjustable rockers is that the the hole is there to pump oil through the pushrods to lubricate the rockers. am i wrong? should my stock pushrods have holes through them to allow oil flow? The old pushrods are solid and therefore have no oil passages.

can someone enlighten me on this because if i put the old pushrods back in i donot want my engine to not get enough oil to the heads and rockers. if i rember correctly isnt there oil passages in the rockershaft stands and in the rocker shaft to allow oil flow?

any help here will be a great help. thanks  

On a 6 cyl motor oil is fed to the valve train by a passage associated to the #4 cam bearing and the head bolts and rocker shaft bolts for #1 and #6 cylinders. Although the lifter has a hole, it not used to lubricate the rockers. 66 ford mustang FSM (pg 8-26). jlg  

Thankyou for clarifying this. i just wanted to make sure everything was correct. Also the old pushrods were a bit rusted, dues to teh fact the engine was sitting on the ground in a barn for approx 12 years before i bought the car. Should i just replace them since theyre not very expensive or clean the old one up and reuse them?  

Your choice, If they're not strucuraly damaged, just clean them up and reuse them or if it makes you feel better, replace them.
