Mild 360 Magnum Build

My next question on your build is what are you doing for oiling system modifications?
The reason I'm asking these questions is I purchased a rusty 5.9 Magnum block and I have a set of flat top 360 Pistons with rods and crank from a LA motor that are 30 over.
So far the only thing I have done to The oiling system is to drill number 2 3 and 4 Passage for the mains out to 9/32.
I’m not doing anything to the oiling system other than putting the right pan on it to fit the car... I will measure everything and calculate the compression ratio before I pull the trigger on the cam in case it’s too low for the one that was recommended to me
