Default Valve covers?

I have and 85 vette and I'm looking for some different valve covers and was wondering if I could use 69-70 Z/28, corvette valve covers, They have the 3 holes? I also found some I like from an 81 vette they also have 3 holes, would these work?

Not sure what you mean by three holes. 85 Vette has 4 bolt holes I think the older covers work if they are not too tall, tall ones hit the Wiper Motor but my covers are the same as all the small blocks I had in the 70s

The 3 holes he is refering to are for the PCV, breather, and oil cap. Yes the older ones will work as long as they are not tall covers, but keep in mind that the holes might not be the same size and you may need an aftermarket breather/PCV setup.
