All Small Six Help! Did I just screw up my new build?

I don’t think 200 come up thru the head bolt. I plugged a passage when I switched to yellaterra rollers which oil thru the pushrods

The oil does go to the rockers up the drivers side rear head bolt hole shared by the bolt by way of a kidney shaped groove in the head. The rear rocker stand head boss has a hole drilled to the head bolt hole. The larger studs does take up more space but it is not usually a problem but possibly could be if it happens to be jammed up against the oil hole to stand boss.
This is why in hotrod building every thing is ported for flow, be it oil, air/fuel, cooling water flow. etc.

I was discussing this with @TrickSix a while back. Here are some photos he sent illustrating how the oil gets through that kidney bean shaped dish under the back of the head to the rocker gallery and then up the post on the rocker shaft tower.

So what did I plug and why?? Rocker shaft supplied by two oil sources?

The first two photos are of the bottom and top side of the head where the oil feeds up the rocker shaft tower. The third photo is of the bottom of the shaft tower where it meets the feed hole. Your photo looks like you've plugged the galley on the block right below the kidney shaped opening on the head. All good as far as I can see.

I would imagine with the Yella Terra set up, you no longer need that feed hole in the photos I posted because the rockers are now lubed by the hollow in the pushrods via the self lubing lifters. Similar to the way a small block chevy or a Chrysler Slant-6 lubed the rockers.
