I've always liked Autolite and Bosch.

I'm in the process of replacing my distributor, wires and plugs as well for the new Unichip I just bought.  When I asked the programmer which plugs, he said "Run Champion plugs as per the factory specs...you can increase the spark
plug gap a little bit more though-maybe an extra .010 over stock."  Maybe it's just due to the Unichip.  Any other opinions?

go champion on mopar engines.  ive seen alot of dyno sheets with spark plug changes.  regular  copper truck plug spark plugs work the best.  I wouldnt mess with the gap,  just keep it stock.
