I have the oppurtunity to purchase a set of completely rebuilt 3.8l heads off an 1988 FWD buick. Anyone know if these heads are interchangeable?

no no and no...why heads ten years OLDER then yours?
Not the same block man.
Valve arrangement tells the story.
Since this was posted... are there any heads that are better for our cars that came stock on other vehicles? Or are they pretty much all the same stockers on series 2, series 3, etc?
Actually, L26 heads are supposed to flow the best out of the entire bunch...being 36/67/32/26
So...if you find some series III L26 heads...get them...have them rebuilt, cleaned up...and ported...and toss them on with some headers if your looking for 20+ WHP gains.
Whoa... thanks man, I'm sure that info will help quite a few people.
