Timing can be done cold or hot, at idle with the vacuum advance unplugged. A timing light is needed and you may find good results wih 8 degrees BTDC. Slacken the distributor retianining bolt and turn it until you get 8 degrees on the timing light.
However you may then think that you could do more........... and this is when you will need the Forum. There are threads on here of great complexity and length about measuring, setting up and getting the most from the timing curve.
You will rapidly descend into a world of graphs, tachs, capsules and flips as you search for that elusive perfect curve.
