Spark plugs
I was changing the spark plugs out in my 82 F150 and saw the ones I was replacing have that V-notch on one of the contact points and when I went to the auto store to get some new ones, they only had the platinum ones that have the regular pin-point look, if you get my meaning. I was wondering, is there any difference in performance between the V-notch and the regular style plugs?

the v notch is a scam. just like the splitfire plugs. also there is no need at all to use a plat plug in your 82. plat plugs are for waste spark ignitions only. they serve no purpose in anything else.

i was reading up, and i'm confused, what is a "waste spark plug?" i always just used standard plugs from parts store, probably autolites or something...
