Engine Blocked cam journal/ saddle

[rockyracoon]

So I'm in the process of assembling my motor after head gaskets and valve seals and I decided to use the garden sprayer method to prime the oiling system, I noticed oil seems to be seeping out of all the cam journals except for the left front most journal so I'm wondering once the motor develops oil pressure that journal will be lubricated or should I go back and remove the cam for further inspection. That head was in the machine shop for a snapped off exhaust manni stud and hot tanked, could some dirt or metal have gotten into the oil passage to that journal?
