I made a similar sketch in my note book when building the engine. My hole is roughly the same location as yours in the bushing. With the 60MM cam and .520 lift the hole is aligned with the oil band at base then below it at the upper lift.

I talked to Ray more yesterday and I feel better about what I have now with its intended use. He gave good advice on what to look for.
