340 Oil Priming Question First Start

Better shot of end of shaft?
Hey I have no background info on this motor. I bought it as is. I don’t know what cam is in it but I did bore scope the cylinders and found 0.030 over TRW 12:1 slugs with what looked like clean tops and the walls looked good. It ran when I started work on the body.
This is a flat tappet set up. Is there a way to identify the rockers and make sure they are properly clearanced
for oil flow? I plan to take them apart and clean them in the morning.

Ps I did see a little oil coming from under the rocker maybe not on all and not so much….
