It can help.  There is a way to read the plug for this alswell as your mixture.  I am pretty sure you look at where the ground is comeing back to the threads.  I am sure there is a big plug tuning guide somewhere.  Maybe a hotrod site.                                 www.sparkplugs.com/faqmain.asp

Are you sure you've got the proper octane and timing you need?  You're not running THAT much compression, dynamic or static.

Here in Mexico u can get only premium that is 92 oct, i cant get race fuel over here thats why but i think i wll be ok whit that coz i have the web 4 it has alot of lobe and duratio, John told me i will be ok at 0 elevation at 92 oct and i trust his word, the reason i ask is coz i think whit the add of comp will create more heat at spark plug.
