O.K., pulled the spark plugs one at a time and unfortunately didn't find any noticable difference in the sound. what this thing sounds like is exactly what valves sound like when they need adjustment. Darin, I don't have the boxes for either the rings or the bearings and what was left over from the gasket set I put into the Fel-Pro box. The enw kit was placed on a piece of cardboard and covered with plastic, no box so I must have threw out the package. I don't tend to keep old shizzit sitting around too long.
