I used a local individual with a machine shop to do the head on mine. He had done several 602 and 603 heads in the past and knew what to look for. Unfortunately he retired at the end of last year. I sent a PM to Nicholas about another possible machine shop in San Antonio, recommended to me by the same guy who did the work on mine.

In other news, the Diseasel got the mixture tuned a bit. Adjusted the ALDA CW about 2.5 turns to get the "coal rolling" under control. In addition to being irritating, the highway fuel economy has been dismal. Doing 75-80mph, I've only been averaging around 18mpg compared to 25mpg or so in city traffic. Since the tuning, I now have ~220 miles on about 1/3 tank of fuel. The same highway driving previously would have me below 1/2 tank. If it does ~25mpg or so on the highway I'll be completely happy.

A/C Update: Still blowing frosty cold. Much appreciated with the hot, humid weather we've been having.

Radio Update: Never going without a radio again. Completely spoiled.

Delivery Valve Update: "See the D/V as source of nailing" thread for full description. Polished the previously nailing D/V's with cerium oxide and oil and swapped them back in Cylinders 1 and 2 on the IP. So far, the nailing hasn't returned. Engine seems to be running fine with them in place.
