Just as well mention that it doesn't matter whether you install the timing chain assembly with dots facing each other or dots up. I prefer installing them close together since it's just easier to visually line them up. Before dropping distributor back in rotate crank one revolution if necessary to get the cam gear with the dot up. Up until the distributor goes in the engine doesn't care whether you have cam gear dot up or down.
If the previous cam was installed without enough clearance the cam and cam bearings will self clearance with the possibility of the Babbitt melting out of the way and forming a ridge at the front of the bearings. If not too bad, pulling on that long bolt and turning the cam with a crescent wrench adjusted to catch the woodruff key might twist the cam out without dislodging the bearings. With the engine still assembled and in the car you don't have many options.
