Should I use theseTelescopic oil return tubes?

I found these in one of the many boxes of parts that came with my recently acquired Porsche.
Assuming I can get new O-rings, would these be a wise choice on my street driven car?

I would never use expandable tubes on a fresh build. They offer 4 more possibilities for potential oil leaks.
I see expandable tubes as a Band-Aid never a proper build option.
If you are forced to use an expandable tube/two I would use the factory version.

Thank you very much for this advice! That was kind of my thought process as well, but I wanted an expert opinion. I will put these in a display case.

Keep them around in case you ever need to remove/replace one of the permanent ones for whatever reason. The expandable ones are the way to do that without pulling the heads (which is their purpose).
