Everything being reassembled and going back together after the rebuild of my 360 motor. After I bought the hydraulic lifters, I decided that I wanted to go with adjustable rockers, as they will give me some future flexibility of adjustment without repurchasing different length pushrods (plus I'm just plain more comfortable with rockers I can adjust - who isn't?). I then proceeded to purchase the pushrod meant for the adjustable rockers, with a cup on one end and a ball on the other, but I noticed that they don't have the oiling hole down the center of them like the original non-adjustable pushrods that I am replacing had. So my questions are as follows:
1. Am I defeating the whole purpose of the adjustable rockers if the hydraulic lifters will keep on adjusting themselves (so to speak)? Should I be looking for solid lifters?
2. Is there enough oil being flung around the inside of the valve covers to where the center oiling hole in the pushrods isn't necessary? Or is this something I absolutely should not ignore?
3. In trying to research this, some guys have put a Holley carb jet in the rocker oiling hole to restrict excess oil and improve oil pressure. Is this a good idea or should I leave that alone?

Thanks in advance.

The oil does not come from the pushrods. It is fed through the rocker shaft assembly.
That oil passage in the head needs a restrictor or your oil pressure will be low to the rest of the rotating mass.

 

Thank you, Christmas. Any idea why the original pushrods would have had such a feature (hole down the center)?
