340 Oil Priming Question First Start

If you are running hydraulic lifters you need to put some angled grooves on the shaft across the oil feed holes.

If you don’t, the rocker will grab the shaft.

Should be done with solid lifters too.
Does the lack of a groove explain my oiling deficiency? The whole reason I am at this point is because I am seeing little to no oil coming out of the rocker arms. Not a drip on many arms.

We jointly found that the passenger shaft IS REVERSED and will need to be corrected.

However now I am dealing with the inadequacies of a modified set up. And I will need more guidance on this mod.
