[genolan]

Just took the car for a nice ride pretty hard and it ran great. went back out and it started to shutter going up the driveway really rough under load. When I rev it in neutral it seems fine with just a little roughness. I turned it off and restarted and it smokes out the passenger headers. The smoke is on the white side with no distinct smell. I did notice that the one spark plug wire was kinda burnt but not melted. Could this be the cause or did something really bad go wrong. I tried to see if the spark was shorting to the header but couldn't see anything. Head gasket?
