Will this work on our cars?

Its says it will fit a 231? (yes I know they mean the RWD Buick 3.8 but I was curious).

I don't think so. My 97 has 3 bolts on the bottom and 2 on the top. I think this is consistent across all years. I didn't read to see if the pic was the actual or merely a chrome representation.

I'd think that the plastic is doing a good job. But that'* me.

IMO the bolt pattern looks different. And if you look at the bonnes intense runs, or gps that zzp runs, i dont think any have chrome covers.....could be a point...i dunno, thats just my opinion

Its not for a performance standpoint. I just always liked chrome valve covers. And think it would be diffrent to have them on then the plastic ones.
