440 build for a tow rig/"muscle" truck?

Kinda random question, browsing the 440Source site I found that they sell a special long drill bit for enlarging the oil passages between the oil galley and main bearings; since the block is already bare and will need to be machined and cleaned should I go ahead and do that? And what about the mods to the oil pickup passages at the front of the block like I see in my MP Engines book?

Also in the parts I got with the engine there is what seems to be a high-volume oil pump that was never installed (just judging by the fact there is a "HV" cast into it). I know with small blocks it's generally not needed unless the engine is modified to need more oil flow and requires the stronger drive shaft, and should be used with a deeper-sump oil pan which I won't be doing, I intend to just use a factory truck oil pan and pickup probably with a windage tray. Should I use it if it checks out good or buy a standard-volume replacement?
