I believe the change to alum heads was a mid 86 thing. I don't think late 86 coupes still had cast iron. So the question is, what else changed mid 86, vs waiting until 87? And of course, the corvette is usually the first to get a change, the other models may lag behind. 1 pc rear seal debut:__86__? alum head debut __mid 86__ roller cam debut __87___? |
