One more thought....
The Indy kit does a great job of oiling the rockers on stock blocks..It wont be much diff than a aftermarket block cause your pulling oil from basically the same place.
You never hear people burning up rocker tips with the stockish style rocker shaft, and the Indy style rocker arms..T&D also..
The few I have seen is with Jesel rockers and spray bar oiling..
I personally have used this system many, many seasons without a single problem..This was a oiling kit I made my self.
So if your setup falls into this category why over complicate things? Sometimes problems we have, is problems we have created.
I would imagine there is tons of people running this setup, and the only thing we hear, is how to cut down the oil they are already getting, not increase the oil supply.
Im sorry if I come off being a smartypants (not my intent), my thoughts are sincere and I do want to help
