Yes, those are the ones. I went on a run on Saturday and about halfway home the car started missing. Pulled the plug wires one at a time yesterday, and determine that the one hole wasn't firing. Pulled the valve cover and the rocker arm for the exhaust valve was loose. Pulled the rest of the plugs and tried to adjust the rocker and it wouldn't pump up. I'm going to fool with it some more this week but it looks like the lifter is either seized or has let go.
