1990 ZR-1 secondary actuators binding?

[mmkkpro]

Hi guys, I pulled my plenum off yesterday to install new parts. So I'm checking secondary vacuum lines and all associated parts and I noticed the actuator arms that attach to the linkage seem to be off center. I know they look bad but they are not leaking down and seem to open properly, however upon releasing vacuum the only return about half way back to the closed position. Is this normal? Does engine assist the return to closed when it's running?
Thoughts on secondary delete? Thanks.
