Default ls1 and ls2 water pumps interchangeable?

Just as it reads. I need one very shortly and want to know if these parts interchange. Thanks!

Default Pull water pump pulley?

I am in the middle of an LS3 376/480 install in a 1972 Chevelle. To fit the Chevelle, I needed to install a 1999 F-body accessory drive, and the damn pulleys don't line up. I have the crank pulley figured out, but this post recommends to pull out the LS2 water pump pulley out about 3/4" to work on an LS1. Which puller do you use to do this? I can't seem to find one big enough.
