340rocker oiling

I was thinking oil feed hole issue. Small piece of gasket scraping? How is the oil pressure on the engine?

Dont some of the head gaskets only go on one way? Maybe those were the older ones. Now they are idiot proof..?? But, he did say they were getting oil, just not much....

Possibly the cam bearing wasnt installed quite right, half a hole off, and hes just now noticing the low oil supply...?
