Bart,

If you want to make sure you got it right ...

Turn over the engine by hand. Make sure the mark line up after turning it over. If that is good. Put your harmonic balancer on and just snug it up and start the engine. Make sure it sounds and revs okay. Don't go overboard and make sure you dont get any loose clothing or hair caught up in the moving parts. This will not hurt your engine and can save you a lot of headache if you didn't get it just right. You know how hard it was to get to where you are now. It would be a pain to have to do it all over again.
