c16se and x16szr channels

Moin, moin has read here several times about the “round” inlet channels from the SE head. Are the inlet channels of the SZ or SZR designed differently? I searched for pictures in the net and always found only heads with just these “round” inlet channels. I had the impression that there are no differences. To explain it briefly. I currently have a x16szr in the car and would like to build on the whole upper part of the c16se like many others here. F I’d like to know what the inlet channels look like on my current head. (Wouldn’t just like to take a look at the inlet bridge) Maybe someone has a picture of it. Thank you very much. P.s.: Please don’t complain, it’s clear to me that this topic has come up very often here. I also have the le I didn’t find anything else to do here to answer the question myself. But I didn’t find anything to look like the one with the x16szr. I already noticed that there are some who already know each other very well and have gained experience. Maybe you can help me.
