1997 Challenger Engine Problem

[AKchallanger]

I would appreciate some help with a problem. When preparing my 1997 Challenger for use I was spraying some sea foam into the cylinders. On the very last cylinder, the plastic tube shot off the spray nozzle and into the cylinder. I tried to retrieve the tube to no avail. I removed the cylinder head and the tube is not in the main part of the cylinder (see pictures please). I am confident that the plastic tube went down the slot at the three o’clock location in the picture. If this is an exhaust outlet the tube may not cause any problems, however…. Can anyone identify the slot and be of assistance?
Thank you so much

3 o'clock position, is a transport hole for oil/fuel. Where the rave is, thats the exhaust side.
