Jeff, I called Dan Diehl and he was kind enough to chat with me for 10 minutes or so.
The issue he had with the motor was aftermarket head studs. He would use 35" for takeoff, 28" in cruise and had run it up to 50" for short bursts. After putting OEM 8mm studs on it, he did not have another problem. Thanks for the tip!
