If you can't tell by the color use a magnet it will stick to the cast heads but not allumium

Magnet

Stock motor changed mid year 86 to aluminum. Your 87 should have aluminum. But if you are not the original owner, you NEVER know what someone has done. Check with a magnet.

All 87s have aluminum heads if they are original.
