I ran tr55s and loved them, I will be going with tr6's on the new build, since it'll be a nitrous car. If I were going to do plugs again on a non nitrous car i would go with ac delco platinums though, better for the long haul, I ran tr55's because they were cheap and I only needed them for a season!

I ran the TR55's on my old set up. They are great plugs. I'm using the Autolite 104's now.

I run my spark plugs in my injector holes, and injectors in my spark plug's

TR-55s for me. 55's and 104s seem to be the common 2 for stock and bolt-on motors. Once you start throwing in cams and more compression, or especially NOS, that'll change.

I have the NGK TR55's in mine, they have several thousand miles on them and still going strong. I'd have to look in my book for exact mileage
