After about 500 miles, I started getting a very rough idle-definitely a miss somewhere in the engine, along with an un-even acceleration and a miss on de-accel. At first I thought something had gone wrong in the head, and took it back to them for the 500 mile checkup....

As it turns out, the fuel distributor was failing on cylinder 2, the SAME cylinder with the burnt and split valves. So, most likely that cylinder was running lean for some time, causing the failed valve. This is a relief to me because I am usually pretty good with the valve adjustments, and was ticked that i somehow messed them up!

A new fuel distributor later, and I have the smoothest idle in the tri-state area.
