timing chain install question

Both #1 and #6 will be at TDC at the same time; so, put either one at TDC, and align the cam & crank sprockets either exactly at 12&12 or at 6&12. (Use a straight edge to make sure the line through both dots passes exactly through the center of the cam bolt.)

If the dots arae aligned at 6 and 12, then #6 is firing so put the distributor rotor one #6 spark tower. If the dots are aligned at 12 and 12, #1 is firing so put the rotor on #1 spark tower.
