Go with the NGK TR55 copper plugs at a .050 gap and you'll be very happy with the results. The stock .060 gap doesn't seem to offer as much throttle response as the .050 gap does.

TR55s with .05 gap worked fine for me.

Agreed as well. If my memory serves me right I believe I actually gapped mine @.055 though. But it's been sooo long since I had the TR55s. With running the juice from time to time I have had TR6s for a good while, gapped @.038. You can't go wrong with the NGKs, they are the most widely used plug around.
