Be sure you understand how this type of filter works. It is basically the same as the original by-pass filter (which is a good filter system). But, it require a restrictor to keep the oil pressure up going to the engine. Without the restrictor you are shortcutting the oil path to the engine and reducing the oil flow.
Also, there is no reason to drill the return into the block. Drilling the oil pan would be much simpler. If I were doing this modification I would put a 90 deg fitting through the oil pan with a short extension on the inside to direct the return oil toward the bottom of the pan.
Update: drilling the oil pan would apply to a 59a block, not an 8ba!
