Oil Pan Seals ??

ok. so I have a question I think i already know the answer too, but before I go farther I want to connfirm this.

I am replacing the oil pan gaskets on my 360.
I know you have the timing /crank gasket and the rear gasket and the side gaskets.......but... when I took the pan off I found two little wedge /_\
shaped gaskets stuck in the gasket sealer at the rear of the pan. know these are approx. 1" long and wedge shaped. I thought these went under the main cap for the rear main seal. . Now I was not the last one to put the pan on so I am wondering what the heck.

Now the pan wasnt leaking from the back and I dont think there is any main leaks. So is this just a weird thing, or do they actually go somewhere before I put the pan back on....help?

anyone?
