Hi.
I'm replacing the cast iron 4" sanitary lines to my two bathrooms with PVC. They drop vertically from each bathroom and turn 90degrees to horizontal in the basement. This turn is via existing long turn/long sweep elbows.

Is there any problem if I switch these to short turn 90 deg elbows? I'd like to regain the headroom in the basement and keep these pipes within the ceiling joist level, instead of having these stick out below the (future) finished ceiling level in the basement. I can't find anything in the plumbing codes on this. All advice appreciated.

There is probably no problem doing that, but just in case, use elbows
with a cleanout.
