You've got a gasket set with cork end seals instead of rubber. The alignment of the end seal and the tab on the side gasket in your second picture is incorrect, as you will probably see if you attach the side gasket to the block instead of the pan. I'd suggest cutting the heads off some 5/16" standard thread bolts a couple of inches long and cutting a screwdriver slot in the ends, then installing them as guide pins at the corner bolt holes in the block. That will align the tabs at the ends of the side gaskets with the end seal slots. Then the end seals will "sandwich" the tabs btween the block and the oil pan, creating an overlapping joint. Glue the side gaskets to the block first, using a contact cement like 3-M weatherstrip adhesive. Then glue the end seals into the grooves in the timing cover and the rear main bearing cap. Put a SMALL bead of RTV sealer at the area where the side gaskets and the end seals meet. Don't overdo it with the RTV- - -a little goes a long way. Use the guide pins to align the oil pan as you lift it into place, and start all the bolts before tightening any of them. Remove the guide pins and install the corner bolts.

A torque wrench is useless here, as the gasket compressed as the bolts are tightened.
Edit: Are the short pieces different widths? If so, use whichever ones fit the slots in the bearing cap and the timing cover and discard the others. It looks like your gasket kit fits more than one engine application- - - -maybe 216 and early 235 and they included end seals of different widths.
