upper intake bolts
After replacing fuel injectors on 87 L98, noticed bolts for upper intake manifold were two different sizes. Do longer ones attach runners to manifold and shorter ones attach to plenum? Or vise versa?

From what I remember the longer bolts go into the corner diagonally holes. They are on the bottom attaching the runner to the intake base. My memory is fuzzy on this, I think there's just four, one on each lower corner and none on the top.
