At one time someone posted this url in this newsgroup about reading spark plugs, http://www.centuryperformance.com/spark2.htm. In looking at my spark plugs, mine look like the "Normal Condition". I run a 355 sbc, 11:1, using autolite 23 plugs, 110 octane gas, 4bbl Rochester 750. I appear to be using the correct plugs through a visual inspection.

Does anyone know of a chart that breaks down "Normal Condition" in more detail so as to indicate what way to go if making a plug change or is this just a trial-and-error sort of deal?

I'm interested in tuning to increase performance by a plug change if that is possible. What is the best way to do this?
