Obviously if both the two dot marks were aligned then it wouldn't run right.

When I pulled the camshafts I installed a service bolt, and it came back with my service bolt still in there. I was careful about aligning the dots on the cam gears (I even put a dot of white paint on the dots to keep track more easily, since they face the firewall).
My concern was about the camshafts being in the correct heads - but they can't go in but one way, correct?
