those 2 are exactly the same size OD and ID but they are bigger than the 90 degree adapter bolt (at least on an LA engine)
small block oil pump gasket claimed
still puzzled about the 2 small brown gaskets at the bottom of picture 1 - they must come in every LA rebuilt kit because I have 8 of the 3 hole ones and 7 of the 2 hole ones!!! I'm pretty sure I have never used them on anything!?!?
In picture one, locate the Carter BBS two barrel mounting gasket. Two gaskets to the left is a small gasket with two different size holes. That gasket seals the emissions tube on later model slant 6 heads.
