Default Are the NBS and NNBS waterpumps interchangeable?

I like the look of the NNBS waterpump over the older style because of the placement of the water neck. I am curious if all the mounting holes and tensioner mount are the same.

The mounting holes for pump to block are the same and i believe the tensioner is the same as well.
