Question Best Spark Plugs for 360?

Am looking for some feedback on plugs. Will be doing a major tune up soon on my '97 Ram with 5.9L, and will be installing MSD components. I'm hoping for suggestions on most compatible and best performing plugs!

I've read a few opinions on different brands in past posts, but I'm always looking for more input, especially from those with a similar setup as mine!

I'm using Bosch +4, and I have a feeling I will never have to replace them...

10.7 360 .030 800 thermoquad headers and all in a dirt car running msd 7al2 Champions at .050 gap. All you will ever need. There's a reason they all come stock with the best plugs already in them so why change.

My 95 Dodge Ram that I bought new in Oct. 94 still has the original Champions in & they have never been touched. I'm not planning changing them any time soon either.

you know that plugs wear out...right? that you do have to change them, at regular intervals?
did you know a fresh set of plugs at the track is usually worth a tenth of a second?
guess what kind of gas milage that equates to...whatever, you pay more, not me.
the bosch platinum plus 4's are just a gimmick. they claim to have the hottest spark because they have 4 ground electrodes...uh...yeah, like there's 4 different sparks going on in there at the same time, right? the spark will just jump the gap between the ground that's closest to the electrode, because that's the easiest path for it to take...so, cut off all the other electrodes, and you will have the same performance with that plug.

platinum plugs are no good for a drag car looking for optimal tune because they burn too hot. one heat range on a platinum plug is equal to 2 or 3 different heat ranges on a copper plug.

champions, autolites, they are all good plugs, i run the ngks because that's what i have been running since my first set of new plugs, and have never had a problem.

Gee I never knew that I could spend so little money & pickup a tenth. It will never happen unless there is a problem with the plugs you replaced. as far as gas mileage goes why doesn't my mileage get worse if I haven't changed plugs. Spark plugs are not rocket science they either work or they don't.

You will get about as many opinions for this as you would for "what's the best beer?" Any name brand plug of the proper heat range will push 100K in any of the later rigs with their thermonuclear ignition systems, unleaded fuel, and the "accurate to a hair on a gnats ass" injection setup.
