Good luck. Worked great for me.
An extra for plug changing: If you have a compressor, blow the loose crap away from the plugs before loosening, as many/most of you know. Additionally, after loosening one turn, blow again. Often, there is crap stuck around the plugs that gets knocked loose when you put the wrench in there and turn the plug. Stuff that dosn't come out with the initial blast. The old-timer trick was to loosen the plugs a couple turns; and, then, turn the engine over a half-dozen times with the starter to let the cylinder compression blow by the plug threads to help clear the junk. I prefer the compressor hose.
