Parts Identification

[TX '90 ZR1]

Does anyone recognize these parts? I think they may have something to do with the EGR system on the later models.
2 are I believe AC Delco # 214-358. GM# 1997212. These were in the boxes.
The one in the center appears identical except it has an outlet with a foam filter on it. No box and don't have a clue for the part #.
Honestly, I am not even sure these parts are applicable to the ZR-1.

All 3 are SPT Solenoid Valves, 2 early styles & 1 late. Yes, all are ZR-1 parts
