I'm still tuning my new 350 with Vortec heads. From what I've researched, vortecs don't like alot of timing advance due to the effeciency of the chamber design. It runs good with 12 degrees static. 055 plug gap is impressive, that DUI must have some power behind it? I had to use accell "shorty" plugs to clear the headers on a few tubes. I also am pulling 15" vac with a mild (256 comp cam).
