How to Assemble the Front of a Small Block

No, only the pass (right) side hole goes through to the lifter galley for oil...

Ok I think I fat fingered GALLEY instead of Valley. I am under the impression that the bolt hole showing daylight is the one that you are putting the bolt with the hole in. You are not putting the bolt into one that would be under pressure correct? That is why I was asking about a shot from the other side (of the valley-rear) not left. I think I have a naked block to look at. I just didn't remember that hole going all the way through.
