Refreshing my memory now looking at the pics I took when restoring the truck almost 10years ago.
This is how the 402 engine was equipped regarding spark plug heat shields.
Only the plugs to cylinder 3,5 and 4,6 had them.
Not saying this is the original set up but it was how the otherwise pretty much untouched engine looked like.
