Rocker shaft orientation?

My research has shown how the shafts are supposed to install, thank you knowledge database! My spidey-senses started tingling about my 273 hydraulic lifter startup and break-in. I pulled both rocker shafts to check for correct orientation. I know notch to the left hand and down and so forth. My question is I think the oiling holes were pointed inward to the manifold and I know they are supposed to point to the valve springs. If the shafts are notched wrong, to I point the oil holes to the valve springs and hang the notch orientation? Compression averages 150# with little variation. Yes, I read the section in the FSM, very ambiguous. Yes, the engine was pre-lubed and top end oiling was verified before startup. 50# oil pressure at idle and 70# at 2500 RPM. I have about 1.5-2 hours run time on the engine now and the distributor recurve and timing are all correct. Advice appreciated as always!--------------DR--------------:-)
