Priming a 340 that's been dynoed a few months ago

Didn't the dyno people provide you with the proper timing settings?
What I really hear you saying is pulling the distributor and getting it back in correctly is out of your mechanical comfort zone?
Basically taking a marker and marking the distributors position and marketing where the rotor is pointing is all that's needed here. I tend to leave my motor setting on TDC (on compression stroke) so I know the rotor is pointing at #1.
Of course any time I do this I recheck timing when I get it restarted.
DON'T be afraid ....
