Spark plug wire routing for a 340 small block.
I don't know what exhaust system you have, but anything that is even vaguely shaped like a drivers side 68-70 340 manifold those would not work with - wires need to stay higher then drop right down to the plugs. I have seen various header routings that stay above the head ports that would have the same issue.
