I have the same Dove tunnel wedge intake and Dove heads and used about a quart of
oil every 200 miles. I could pull off the carbs and look down the runners and see the
oil on the top of the valves. When I pulled the intake I noticed that the gaskets were oiled. I also had trouble once in a while with the idle. Classic intake leak. I talked to Mike at Shelby Enterprises and he said that there is a known problem with aluminum heads and intake sealing. I found that by continuing to retorque the intake my problem has gone away. I don't know what the torque value is as I did it by hand after bringing it to spec with a wrench. It is much higher than recommended. If you choose to go this route make sure your intake bolts are as long as possible. I worry about pulling the threads out of the Dove heads. The clue for me was the idle problem, most of the time it would idle OK but once in a while it would idle high.
good luck.
