My vaccum line is to short to reach to other vacc. port on the carb.
I have it on the left one now because it reaches there, but the install manual says I should have check the hose while running to see if there was vaccum or not.
I think I should get the vaccum hose on the right port first but I'm not sure which one to use.
Then I'll get out the timing gun and turn the dizzy till it stops pinging
Then I'll tune the carb.

You should check the timing with the vacumn hose disconnected from the dist and plugged. While engine is running unplug the line and see if it has vacumn on it, if no vacumn at idle it is ported vacumn. If it has vacumn at idle it is full time manifold vacumn. Many discussions over the years on which is best. Try it both ways and see how your engine performs.
