What Are These Parts?
 

I am doing my first engine rebuild on my 2004 RSX K20A3 engine and having taken it apart down to the engine block. I ordered Engine Gasket Kit DNJ FGS2016 from JC Whitney and have found some gaskets that are not in the shop manual or in my collection disassembled parts. Any help would be appreciated.

Part "A" is the seal found between the plastic thermostat housing and the aluminum water pump housing. Part "B" is the oil seal found on the back side of the timing chain cover which seals an oil passage on the block.
