Bad gaskets?

[The Guz]

When you install the coolant elbows use some vasloine or something to lube the o-rings so they don't get damaged.

This is the part number for the OEM elbows:

Picked them up at the stealership on the way home. I think I need some vaseline after that trip.

I know which is the upper and which is the lower elbow, but which end of each elbow goes in the bracket and which goes in the manifold? It looks like the ends are slightly different sizes, and I just want to make sure I am popping them in the right way. Perhaps that is my problem on the replacements--could I have the wrong end in the manifold? The autozone pieces seemed like they were the same size on each end of each elbow if I remember correctly. Anyone recall which end goes in the bracket and which goes in the manifold?
