Water pump replacement

[Guest Anselcop]

I'm in the process of replacing the water pump on my 1949 with a straight 6.  The water pump came with a new plate that has a raised boss area around one of the bolt holes.  I have a full gasket that goes between the pump and the plate and a smaller half gasket that goes between the block and the new pump. So to make sure I understand what the raised boss around the bolts hole is for, I'm assuming since the gasket between the water pump and the block only makes contact with half of the surface the raised boss will make up the thickness of the gasket since there is no gasket around the raised boss bolt hole?  Hopefully I don't confuse anybody...
