somebody please educate me on this

I read that a 6 blade water pump is for an a/c car and an 8 blade water pump is for a non a/c car. I just pulled the pump on this non a/c 440 and it has a 6 blade pump on it. The new Milodon high volume pump I bought from Summit is an 8 blade pump. Is this gonna help my water problem or does it even matter.
