My 175K engine has the biggest ridge I ever saw on the top of the cylinders but it still doesn't puff any smoke. I'm kinda curious how far it will go. I still tow cars on 1000 mile road trips with it. I seem to have plenty of power for towing cars but if I lived out west with bigger mountains I may be wanting for more power. You do have dual exhaust don't you? Mine just has a Performer cam and headers.
