Well, reading your post, I take it you are asking if special preps are needed to the oil pump? I can't see why. I would buy a quality stock pump, bolt it on, and forget it.

If this was a drag engine, or other severe usage motor, then maybe a good blueprint job and matching the oil galley holes. But not for normal usage, even in a heavy duty application like this.

Some of the others on here who are true engine experts may have some other thoughts, but I thought I'd give you a bump to bring this thread some extra life.

Good luck.
