Probably worth getting an uprated pump as you're replacing anyway - if I'm correct you only need an uprated pump if you have larger bearing gaps (e.g. race bearings with different tolerances) however I am open to correction!
Cosworth/RCM oil pumps get a lot of good press however all you need is one with the pressure valve shimmed! Which is a hell of a lot cheaper, I may have a contact who can supply one if needed. Who are you getting to rebuild your engine?
