gsr head obd1 or obd2

[Dylan423]

hey guys I have a quick question about a gsr head I bought a while back. I don't know what year it was off of so is there any way to tell if it's obd1 or obd2. it's just the straight head nothing else. I'm thinking about getting a obd2 gsr block but I just want to make sure this head would work on it. I know mechanically it will but when it comes to sensors and all the other stuff, I'm in the dark. any feed back would be great thanks!
