To get the oiling correct on Chrysler rockers with Chrysler oil timing, you MUST apply machinists bluing and then assemble every rocker on the shaft with soft springs holding the valves on the seat. And the adjusters need to be removed.
With that done, you need to look through the hole in the rocker arm that feeds oil to the adjuster and cup and you MUST see the hole in the shaft through the hole in the rocker complexly. The hole in the rocker must be 100% open to the hole in the shaft.
If it lines up, you don't need pushrod oiling and all you are doing is increasing the the needed lil flow the pump has to put out.
If the holes don't line up, or you can't see them, you need to stick a small scribe into the hole in the rocker (while making sure the valve is on the seat and the rocker is at zero lash) and scribe onto the shaft where the oil hole needs to be.
You can not groove the shaft or anything else. You must have full pressure oil flow out that hole while the valve is on the seat and you can run the RPM's as high as your testicles and/or wallet can handle.
If you do that, push Rod oiling becomes an redundant unnecessity. And push Rod oiling is no better if the oil timing to the adjusters is correct.
