well, i didn't take anyone's advice and ran the stock heat range until i had pre-ignition and half of the porcelin broke off inside the combustion chamber and twisted the electrode! 
ever since then i run anywhere from 1 to 2 stages coler (autolite, works best for me and a few others here) depending on what the plugs look like
