I found two listings for plugs one for aluminum heads one for cast iron. Do all 88 vettes have aluminum heads. Mine is stock, they look like aluminum heads but not sure. If both cast and aluminum heads used is there any easy identifiers???

I'm pretty sure all OEM '88 vettes came with aluminum heads. Use a magnet to determine exactly which you have so you can be sure. If iron the magnet will stick.....aluminum it will not.
