I believe all verts in 86 had aluminum heads. Take a magnet and see if it is pulled to the heads.

It depends.I believe the '86 had iron heads until February of '86.Check your tag on the inside of the driver's door.You should be able to tell.Good luck.

umm. Yea I saw this and checked mine. My car was made in november 1986 because I have the removable top and I took the felt off of it inside because its not a clear top and it said it was made in 11/18/86. I changed out valve covers but they are on the corners of the valve cover and the spark plugs I install are for cast iron. Why if my vettes a late 86 I guess have cast ironn? Will my VIN number help you guys help me figure out whats up?
