Default Big Block Swap, Water Pump Question

So i have a bit of a special case which is why i wasn't able to find the exact answer on the forum. I have purchase a Chevrolet Performance 427 Anniversary Edition Big Block All Aluminum motor in which i am putting into my '79. The motor comes with nothing for accessories so im doing it from scratch. The motor came with a short water pump and im looking at getting a March Performance Pulley kit, how ever it seems with the short water pump kits on the corvette you have to run the GM Type 2 power steering pump with remote reservoir as apposed to the normal Saginaw Power steering pump in which is easier to deal with plus i really like the clean look of it. Although i feel like this is an easy answer i just wanted to run by you guys, if i go ahead and buy a Long water pump to replace the short one it comes with and then buy the pulley kit accordingly for the long pump, i shouldn't have any issues im not thinking of correct?

I have a March setup and it works great. I have the type II PS pump. I prefer the type II since I don't have to move/remove the alternator to check the PS fluid (you can see my reservoir in front of master cylinder).

I am also running the Edelbrock 8852 water pump. Standard rotation, short pump. The March setup uses a standard rotation pump for non-A/C and reverse rotation for A/C. Not sure what GM delivered with the 427 crate.

Not the best pic, but you get the idea. Just make sure you get high flow pulley setup (smaller crank pulley to increase water pump speed).
