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.
