Mounting New water pump on slant 6

I am near to putting some of the items back on this slant 6 i have on my stand. I bought a new water pump, but need to ask a question before I go mounting this thing on the block.
When I opened the box, I noticed that there is the water pump body. I flip it over and see that there is a back plate that is held by the water pump blade. In between the water pump body and this plate, there is a gasket. Does this gasket also need to have sealant on it?
I know when I attach the waterpump assy to the block, there will be another gasket and sealant betwen the housing and the block.
No you do not need sealant on the inner gasket because there is two new Surface.
