Changing spark plugs in a small block 360 Any recommendations on which brands are the best to use?

[1] NGK pioneered the copper centre electrode.
[2] They didn't foul up like Champions did in Jap bikes
[3] I remember Champion magazine ads rubbishing the copper NGKs. Now Champion & others all use copper...
[4] Every brand of plug I have seen is plated, never bare steel
[5] Plat, Irid & fine wire plugs require less firing voltage. The benefit for the hot rodder is a bigger plug gap.
[6] Correct heat range for Chry V8s & 6s is a '5' in NGK, which is what I would use.
