Now the next question - should i upgrade to HEI for more power, reliability, and ease of maintenance?

If you want to upgrade the ignition then go to a msd 6al-2 and msd pro billet distributor. You can also adjust the mechanical advance curve to where your motor needs it. Much much better than an hei. If you must have an hei then use the msd pro billet hei. http://m.summitracing.com/parts/msd-8365
