1977 452 heads stock springs

Everything is stock and I'm just reassembling it. Half the springs have a damper and the exhaust valves are supposed to have rotators. I just need to know if the exhaust or intake springs had the dampers.

Compare the spring heights. See if one is shorter than the other. If so, the shorter springs will use the exhaust rotators and that will answer your question. I've never seen one that had eight of one with dampers and eight without, so I would be looking at the heights.
